Green Tree Blvd. Extension w/new bridge over BNSF
Main Tracks at Victorville, CA

close to: "natural crossover / flyover" at MP 39.1 of the BNSF Cajon Sub
After years of planning and searching for funds, our local Governments have started construction of the fifth roadway between Apple Valley and Hesperia (and / or Victorville). These projects are necessary, not only for normal vehicular traffic but, for emergency traffic in this VERY earthquake prone area. Three of the roadways have existed for many years but one accident would clog the other two roads for hours.

The s
omewhat recent fourth project was the BNSF RR bridge built over the extension of Ranchero Rd -- as previously documented:

The hyper expensive factors in this construction are that all five, of these arterials, must cross the
normally dry Mojave river, its tributaries and the very busy BNSF RR Cajon sub-division. What's important to we Raifans is that this latest construction must cross the tracks very near the "natural crossover / flyover" at MP 39.1 of the BNSF Cajon Sub -- and how the new roads will affect the hill overlooking the flyover (our viewpoint, locally known as "Gray's Hill").

I have edited a couple of local Government maps and added a few pictures showing the project's current status and its PROPOSED route --- which will cross the BNSF. Unless you've visited the area, you may find all of this confusing. GGG

Green Tree Boulevard extension closer to construction - News - - Victorville, CA

VICTORVILLE — Barring obstacles, the third phase of a multi-million dollar roadway project connecting Victorville to Apple Valley will begin in July 2020.
The City of Victorville announced that it has received the necessary permits and permissions needed from BNSF for the Green Tree Boulevard extension project that would include an overpass constructed over the BNSF railroad tracks and wash adjacent to tracks.
The nearly one-mile project will connect Yates and Ridgecrest roads in Victorville, located near Mojave Narrows Regional Park and Spring Valley Lake, with the intersection of Hesperia Road and Green Tree Boulevard, also located in Victorville.

With construction and improvements to the Green Tree Boulevard and Hesperia Road intersection, the estimated cost to extend Green Tree Boulevard is $45 million. The city will be responsible for 49% of the project’s overall cost, with the San Bernardino County Transportation Authority providing the rest.
The SBCTA will loan up to two-thirds of the funding — estimated at $12.5 million — for the city’s share, with the city paying back the agency in road development impact fees, the city reported.
The city will also receive funding from the Town of Apple Valley and the county totaling about $4.8 million. An additional $4.2 million from federal funds will also assist the project.
The Green Tree Boulevard Extension is considered Phase III of the Yucca Loma Road/Yates Road/Green Tree Boulevard Transportation Improvement Project.
Phase I of the overall project included the construction of the Yucca Loma Bridge over the Mojave River, which connects Apple Valley to Victorville. This phase also included the widening and improvement to Yates Road in Victorville, which skirts the north end of SVL.
This portion of construction involved the Town of Apple Valley and the County of San Bernardino.
Phase 2, dubbed the Yucca Loma Road Widening Project, expanded the roadway from two to four lanes on the stretch from Apple Valley Road to Kasanka Trail. It also provided other improvements and a traffic signal at Yucca Loma and Havasu roads in Apple Valley.
In May 2017, the Yucca Loma Bridge was opened, with Phase I and II of the project completed. Since that time, many have applauded the partial completion of the project for the addition roadway that connects Bear Valley Road and the SVL area to Apple Valley.
Others have voiced frustration over the uncompleted project that has increased traffic congestion near SVL and for commuters driving eastbound on Bear Valley Road as they attempt to turn left onto Ridgecrest Road.

The Demise of Gray's Hill  -  Part 3
If anyone remembers 'The Demise of Gray's Hill' photographic project started in 2016 ??
It looks like 'they' (Victorville) are finally getting serious about "The Demise of Gray's Hill" and the completion of the latest road from VictorVille to Apple Valley.
Drove up to "Gray's Hill" today (7/05/20) and there is activity between Hesperia Rd (to the West) and the BNSF tracks.
Of course, the slowest & most expensive part of this project will be the Bridge over the BNSF.
Two projects going -- I may earn my COVID BREAD & WATER.

The Demise of Gray's Hill  -  Part 4

Back in 2016, I started a new photo series “The Demise of Gray’s Hill” in conjunction with a rather large local Government project to provide a fifth roadway between Apple Valley and Victorville / Hesperia / I-15.
These projects are necessary, not only for normal vehicular traffic but, for emergency traffic in this earthquake prone area. Three of the roadways have existed for many years but one accident would clog the other two roads for hours. 
The hyper expensive factors in this construction are that all five, of these arterials, must cross the normally dry Mojave River, its tributaries and the very busy BNSF RR Cajon sub-division. What's important to we Raifans is that this latest construction must bridge the tracks very near the "natural crossover / flyover" at MP 39.1 of the BNSF Cajon Sub---and how the new road will affect the hill overlooking the flyover (our photographic viewpoint, locally known as "Gray's Hill"). 
This latest project is being built in three phases: 
Phase #1: (Apple Valley) includes widening & improving Yucca Loma Rd and building a 4 lane vehicular bridge across the Mojave River --- COMPLETED
Phase #2: (County of San Bernardino) includes widening & improving  Yates Rd --- COMPLETED
Phase #3: (Victorville) will include extending Greentree BLVD and building a 4 lane vehicular bridge across the BNSF CAJON SUB --- under construction

Edited Google Earth of entire project. - 020
In the Phase #3 are --- Greentree BLVD extension (PURPLE), the area of the new vehicular bridge, and “Gray’s” Hill are shown. The “G” at the lower center is the approx. location of the Gray residence.

UP 7630 WB passes Gray's Hill.
Since the first of the year, a homeless encampment has been GROWING across the tracks - to the West of the Hill. Last time we were on Gray's Hill, the camp occupied 2-3 acres and contained 10+ junker automobiles, 3 junker motor homes and tons of trash and debris. Victorville obviously tired of the mess and mounted a cleanup campaign. The City brought in 4 Sheriff's patrol cars, 5 large dumpsters, and a front-end loader to cleanup the mess.
MF 9/15/20 - 025
UP 6762 (DPU for UP 7630) is WB. Noting how much higher the tracks are above the creek bed and that they are about level with the hill to the West, we are wondering just how far back the Bridge will start on the Western approach.

For those who were not with us or have forgotten, the project to provide a new road connection between Apple Valley and Victorville was begun in 2015. Phases #1 (Apple Valley) & #2  (San Bernardino County) have been finished, leaving only Victorville's Section (#3) to be completed.  GGG

Visualization of Green Tree Extension Bride over BNSF Tracks - Victor Valley News Group - 040
The following information (from Victor Valley News Group) was released on 1 June 2001 (see below).

VICTORVILLE, Calif. — Today, the City of Victorville announced that it will break ground on its Green Tree Extension on June 2. The City will extend Green Tree Boulevard 1.5 miles from Hesperia Road to Ridgecrest/Yates Road connecting the communities of Victorville and Apple Valley. The Green Tree Extension will create another East/West corridor benefitting the Victor Valley and providing much-needed congestion relief to Bear Valley Road.
Today, the City of Victorville hosted a Groundbreaking ceremony to celebrate the start of construction on this capital improvement project. Due to health order restrictions on public gatherings, attendance at the event was limited.
During the Ceremony, Victorville Mayor Debra Jones expressed the City’s enthusiasm for starting work on this project that has been 50 years in the making.  The Green Tree Extension was first envisioned in the 1970’s. The project was added to the Victorville General Plan in 1988 and became a viable project in 2007.

Integral to the project is a 600-foot-long bridge that will travel over the BNSF railroad. When complete, it will be the longest bridge in Victorville. City officials estimate more than one million pounds of rebar and 24 million pounds of concrete will be used in the new bridge.
The City will add a traffic signal where Green Tree Boulevard connects with Ridgecrest Road and widen Ridgecrest to four lanes. The intersection of Green Tree Boulevard and Hesperia Road will also be widened, and new turn lanes will be added.
Bike lanes will be added throughout the length of the project creating a larger bike lane loop nearly seven miles long connecting the Mojave Riverwalk to Hesperia Road and 7th Street.
The City expects to use nearly 55 million pounds of asphalt and close to two billion pounds of dirt for the bridge and roadway combined.
“To bring an engineering marvel of this magnitude to reality requires not only great engineering, but also great vision, teamwork and collaboration,” said Victorville Mayor, Debra Jones. “We are extremely grateful to the Town of Apple Valley, County of San Bernardino and San Bernardino County Transportation Authority for helping us make this vision a reality.”

The Green Tree Extension will be completed for a total cost of approximately $46.8 million. San Bernardino County Transportation Authority will contribute $22.7 million, the City of Victorville $15 million, the Town of Apple Valley nearly $4 million, and the County of San Bernardino approximately $900,000.  Additionally, a federal earmark of $4.2 million originally designated for the High Desert Corridor was authorized for construction of the Green Tree Extension.

To pay its portion, the City of Victorville has contributed $6.6 million in cash and is financing the remaining portion via a loan agreement with SBCTA that will be paid off utilizing future road development impact fees.
The City’s construction contractor, Skanska USA will break ground on the project June 2. Construction is expected to take 22 months to complete.

Located in Southern California at the high-point between Los Angeles and Las Vegas, Victorville is the leading city for both industry and retail in the High Desert region. Victorville is a growing, vibrant community that is home to approximately 125,000 residents and some of the area’s largest employers. Clean air, abundant mountain vistas, family-friendly recreational activities, spectacular sunsets and breathtaking night skies entice locals and visitors alike to fall in love with this city that is within a few hours of SoCal beaches, National Parks, mountain retreats, and other major attractions. Ontario International Airport is less than an hour away. Learn more about the City of Victorville at

9/01/21: The Demise of Gray's Hill  -  Part 13
The ATTACK on & DEMISE of GRAY's Hill, & its RailFan overlook, continues unabated. A newly planned Mojave Narrows Senior Assisted Living Center will be sited as shown in photo #093. According to the Geo-Technical documents --"This California senior living center will feature four buildings: an assisted living facility, an independent living facility, a rehab center, and a medical center".
The few environmental documents I've read make no mention of the entire area being a FLOOD PLAIN. Also receiving little mention is the "normally dry" creek-bed between the site & Yates Rd which, very occasionally, can become a raging river.  Maybe the rehab center will offer swimming lessons???
At my age, consideration of a West facing, second floor apartment, overlooking the FLYOVER sounds reasonable. Of course, by the time this project obtains all the Kalifornia & Federal licenses, we all may have found that final resting place.

9/19/21: The Demise of Gray's Hill  -  Part 15
Sunday (9/19) was a beautiful day on Gray's Hill. Not much to report construction wise, except that Skanska Construction Co is building some HUGE steel pipe backed wooden forms for future concrete structural and retention walls.  MF & GGG
# 117 & # 118: are from the top of the hill, looking west at the entire project. In the foreground, pieces of the above mentioned steel pipe backed wooden forms may be seen.
Since we do not know the future of the Gray's Hill overlook as far as elevation or access, we have decided to "over-document" the FLYOVER, from the current elevation. The three trains we photographed were all BNSF, West-bound, and GE/Webtec powered.

The Western bridge abutment is being "formed-up" for the concrete pour. The concrete blocks and metal poles hold the forms stationary & vertical for the pour. My CAJON ROVER #2 was the official vehicle for this train spotting activity.

Marc & I had a great 10 train 2.5 hour morning in and around Gray's Hill last Saturday (Dec. 11th).  GGG & MF
# 223-224: LAST November 25th, we could not identify the black devices attached to the wooden forms (white arrows) and asked for ideas. Friend Gordon G. answered with the following information:
The black objects are fittings used in prestressing the concrete beams of the bridge. When the forms for the beams are in place, they'll contain rebar and also long metal tubes that run the length of the bridge. They will be near the top of the beams over the columns, and near the bottom of the beams between the columns, and they will attach to the black fittings. After the concrete has set, steel wires will be run through the tubes and tension will be applied to them. This will put the surrounding concrete in compression.
GGG - 12/11/21 - 223 GGG - 12/11/21 - 224
# 225-227: Gordon was correct and Skanska is building the bridge to his specifications. In # 226, The red arrows point to the rebar cages that will strengthen the horizontal concrete beams. The white arrows point to access points to the tubes, through which the steel tension wires will run. THANKS GORDON

Last week, I received an E-M from Jorge L. stating that there were 30+ huge dump trucks carrying loads of dirt away from Gray's hill.

Forms have been partially removed from the interior walls of the Western Third of the bridge support structure. 
We questioned the purpose of the hundreds of long pins/nails/screws that protrude from the concrete and/or the forms until we received the following from Gordon G:  "I think the wires sticking out of the concrete were used to keep the forms from bowing out from the pressure of the wet concrete. Some can be seen sticking through the forms. I imagine they'll be cut off"

2/26/22: The Demise of Gray's Hill  -  Part 31
Last Saturday was interesting at the "Gray's Hill" bridge project.  While Marc is up documenting the OLD & long abandoned Tonopah and Tidewater Railroad ROW between Ludlow, CA and Death Valley, Jorge & I had 10 trains in 2 hours locally.   GGG & JL
# 340-342: We could hear our first train slowly laboring up the approximately 1% grade between Frost and the Flyover long before we could see it. The lead three units appeared, pulling a VERY Long (60+ cars) and VERY HEAVY CEMEX aggregate train WB. The Three trailing DPU's sounded to be generating FULL POWER in "RUN EIGHT??" The sight & sounds of this very slow train were something rarely seen or heard on the normally high speed Cajon Sub.

# 347-348: We think the newly installed wooden cross beams will help support the bridge deck concrete pour. In Vol #30, we questioned the many wires protruding from all of the concrete support beams (white arrows in both pictures). Friend Bob W. sent the following explanation:

Gary: Those "Wires" are called Snap Ties. They are designed to break off approximately 1 inch back in the wall. If you look closely you will see a conical void where a plastic spacer in imbedded in the concrete when these are removed a laborer goes back and fills them with a special grout so when done it is all smooth and teh Ties are not exposed to the air.   Thanks Bob.

BNSF 8186 WB at Frost - first part of double train
# 349-351:1 Our second INTERESTING train was actually a DOUBLE TRAIN --- two separate trains coupled together and controlled by the ONE crew in the lead diesel. So BNSF 8186 & BNSF 6331 are WB through Frost as ONE TRAIN.

Last Sun, was a beautiful day in the Mojave. Normally, we've been hitting the Bridge Construction Project twice a month but it way too nice to stay home --- & besides, it's NOT FOOTBALL Season.   GGG - MF
# 352-353: The Construction forces have been busy lowering the lookout point on "Gray's Hill". Many many railfans have used this area to photograph trains on the famous ATSF / BNSF FLYOVER near FROST. Upon our arrival at the Overlook, we were met by BNSF 6867 WB pulling a very long string of (probably) empties. If you will remember the "old" pictures taken from the overlook, the crest of the hill is now much lower.  We will determine how much has been removed shortly??

New questions: What is the function if the one foot diameter pipe which apparently will run the length of the bridge (on both sides).

Secondly, after the deck is poured, all of the wooden supports will essentially be trapped in the concrete "tubes"--- How will all of that wood be removed or is it left in-place for some future CIVIL ENGINEER to laugh at our ancient building techniques?
BTW #02: it appears that enough wood has been used in this construction to build a small suburb.
BTW #03: we see no inspection or drain ports in the concrete floors or walls of the support structure ???

3/19/22: The Demise of Gray's Hill  -  Part 33
Last Saturday (March 19) was a cool & very windy day.  While Marc was attending WINTER-RAIL MEET in Corvallis, Oregon (, I decided to make our normal photo circuit to the GreenTree Rd extension and the new bridge across the BNSF Transcon.   GGG
# 370-372: From high on the Eastern bridge approach, the entire bridge is pictured. Rebar erection is nearly complete on the Eastern third, while forms are being applied to the completed rebar "cages" in the middle section. More on the Western bridge third later in this report.

Near the West end of the new bridge, a major tributary of the Mojave River flows under the Greentree Rd extension and both tracks of the BNSF trans-con. While both the River and its tributaries are normally dry, the infrequent MAJOR storms turn both into raging rivers---thus, this spillway with current disturbing RIP-RAP.
# 373-374: The only vehicle friendly track crossing is one mile RR East at FROST (MP-38).
On the way, I took two pictures of the new bridge (MP-39.4) through the Flyover Bridge at MP-39.1.

# 378-379: Pictures of the bridge Western third with the false bridge deck plywood floor partially in place. Since pouring of the concrete bridge deck will provide five SEALED concrete "tubes" in each third of the bridge support structure, what happens to all of the wooden supports trapped within the tubes? We also asked the function of the large metal pipes running the length of the bridge within the two outside concrete tubes.  The answers below come from Bob W.
Gary the large pipe running the length of the new bridge is for utilities mainly electric conduits for future lighting. As to the plywood deck and supports they will be left in place as there is no way to retrieve them That structure is referred to by the name of Lost Deck because you are losing all the material it took to form it up. Hope this helps.    Bob W.
I guess some future Archaeologist will have a GRAND TIME studying our  PRE-HISTORIC building techniques.  GGG

We could not get into the construction project as Saturday (4-2) was a Skanska Construction Corp work day. BNSF train traffic, however, was heavy.   -   GGG & MF
# 380-381: From the "Gray's hill" overlook, the junction of the GreenTree Rd. Extension & Yates Rd. is pictured. Hopefully, the road widening & curvature reduction will reduce the current number of serious accidents at the current curve. Of course, drivers now will have to deal with a very  steep hill --- from the camera position down to the junction.

GGG - 4/10/22 - 397
Awhile back, we asked the function of the metal rods protruding from the concrete walls of the support structure. Bob W. answered our question with the below:

"Gary Those ”wires” are called Snap Ties. They are designed to break off approximately 1 inch back in the wall. If you look closely you’ll see a conical void where a plastic spacer is imbedded in the concrete when these are removed a laborer goes back and fills them with a special grout so when done it’s all smooth and the Ties are not exposed to the air."
Yesterday, we found a large carton of these "SNAP TIES", one of which is pictured. The features Bob mentioned, are prominent on pictured object.  -  Thanks again Bob.

GGG - 4/10/22 - 398
These unknown devices / parts were found near the Eastern Approach to the bridge. They are stamped "SKANSKA - 180 Lbs". Our "WAG" is that they are the end devices which will capture and hold the cables of the concrete POST TENSIONING SYSTEM ??

5/01/22: The Demise of Gray's Hill  -  Part 37
Sunday (May 1) was a beautiful day in the Mojave. After finding nothing really new at the bridge construction site, Marc & I drove down to the Kemper-Campbell Ranch at Frost (MP-38). BNSF has been replacing rail in the area and had temporally removed the FROST road crossing & the Dragging Equipment Detector (DED). For the last week, BNSF has been single tracking through this area.  MF & GGG

5/22/22: The Demise of Gray's Hill  -  Part 39
I wasn't going to send these few pictures, but with the horrible events of today May 24 (mass shooting in TX), I wanted a constructive outlet. Last Sunday, Marc was showing a new (to this area) railfan the bridge construction and the area locally known as 'The Gray's Hill Overlook'. So, I joined them and we photographed a couple of interesting new developments in the bridge project.  -  GGG & MF
#446-447: Two of the NEW & much LOWER elevation of "Gray's Hill overlook. The original overlook was at the level of the hill at the far right (arrow).  We estimate that the overlook area is now 30 - 40 feet lower.
GGG - 5/22/22 - 446 MF - 5/22/22 - 447
#448-449: I had wondered what happened to the large wooden forms used to form the walls of the bridge support structure. Skanska simply flips them to to the top and they become the floor for the deck pour.  As mentioned, all of that wood will be sealed within the concrete support structure--never to be seen again (in our lifetimes).

Last Sunday (May 29) was a very cool, windy and dusty day. Trains were backed up at BNSF FROST due to single tracking, somewhere East of Victorville. Skanska is getting close to pouring the concrete bridge deck.  We were surprised at the many tons of REBAR used to strengthen the deck.   GGG & MF
#452: A project view WEST from the Eastern bridge approach. Rebar placement on the Western & middle bridge thirds appears to be nearing completion. Pictures #453 & #454 (next) were taken from the highest point on the newly paved road in the upper right of #452.

6/18/22: The Demise of Gray's Hill  -  Part 41
Real visible progress on the bridge on a day where train traffic was extremely heavy. Skanska Corp has started pouring the concrete bridge deck and we ran into a Construction Foreman who was willing to answer a few or our questions.
Skanska was working over the weekend and a 'white hat' (Boss type) approached - presumably to evict us . Using all our "Desert Rat charm" & explaining that we were documenting the construction, he became very friendly and talked with us for about 15 minutes. Here are the highlights of our conversation:
*A): The bridge should be finished next month.
*B): The bridge will have a six foot pedestrian / bike lane on the South side and a twelve footer on the North side. Both of these lanes will be guarded, from traffic, by a concrete barrier AND have some kind of fence on each outside.
*C): The deck concrete will be 9 & 3/8ths inches thick.
*D): "The TEREX Concrete Paving Machine does a much better job, faster than any of the OLD techniques"
*The POST-Tensioning cables will be added and tensioned AFTER all concrete has been poured & allowed to "setup some". I asked how they would get the cables through the tubes since the tubes were installed in a kind of 'gentle roller coaster' (UNDULATING) fashion and encased in concrete. He smiled and mentioned that they had some kind of crawler machine that would pull the cables through---as long as the tubes were still connected.
First I thought we'd show just how much dirt has been removed from Gray's Hill.

Post-tensioned concrete is a type of prestressed concrete where the concrete is strengthened via an arrangement of reinforcement held in tension. Steel cables, called post-tensioning tendons, are placed in plastic sleeves and positioned inside the concrete formwork before the concrete is poured. Once the concrete is poured and gained sufficient strength, the cables are pulled at either end (tensioned) and anchored on the outer edges of the concrete.   THANKS TO BOB W.

7/23/22: The Demise of Gray's Hill  -  Part 45
I've been all over the "NET" & YouTube trying to make sure we have the nomenclature of the bridge post tension parts and processes correct.  I understand that MOST of you are not interested in Concrete Bridge POST STRESSING, but here is what I came-up with - (Marc made me do it ?????)
#510 & #511: Looking over the ramp from the future GreenTree/RidgeCrest Rds intersection. This area has been lowered 50+ feet.
The ramp is now nearing a reasonable angle of assent/dissent.
MF - 7/23/22 - 510 (see above) MF - 7/23/22 - 511 (see above)
#512 & #513: From the EAST (ANCHOR) END. There are seven rows of portals, each row has three portals which hold the "tendons" (cables) for the tensioning process.  After threading the tendons through an "Anchor Block", each 'tendon' has a 'anchor wedge' attached. The wedge, surrounding the tendon, is then fitted into the anchor block - tension will cause the wedge to expand & prevent the cable from pulling through the block.

MF - 7/23/22 - 512 (see above)

MF - 7/23/22 - 514 (see below) MF - 7/23/22 - 513 (see above)

#514: From the WEST (WORKING) END. After threading the tendons through another "Anchor Block", 'Anchor Wedges' will be fitted to each tendon. The hydraulic tensioning device (#515 & #516) will be moved into position and attached to the tendons. A prescribed amount of stretching / tension force is applied to the tendons, the wedges moved into position and the Hydraulic device removed.

MF - 7/23/22 - 515 (see above) MF - 7/23/22 - 516 (see above)

#517: QUESTIONS: We cannot identify the machines pictured in #517. There are 21 of them, which corresponds to the number of tension tubes. We wonder if these machines had anything to do with threading the tendons through the tubes???
From what I read, grouting within the tension tubes is of the utmost importance in preventing tendon rust & bridge collapse. We find no way for the contractor to introduce grout into these tubes. Could it be that, since this bridge crosses no body of water & only faces 3-6 inches of yearly precipitation, grout is not needed ??

MF - 7/23/22 - 517 (see above) MF - 7/23/22 - 520
Inspector Marc OK's the progress--so far
#518: BNSF 3964 +3 leading and 3 trailing DPU's is WB with a very very long ethanol loads (the BOMB). I didn't notice the CROSS until I edited the pictures--Here is what I found: Michael Slavin Victim in Victorville ATV Train Accident

#532 & #533 The EASTERN Bridge wall serves as the ANCHOR for the 21 sets of "tendons" (cables). These tendons, when tensioned (stretched) serve to strengthen the concrete structure and to prevent concrete cracking. #533 shows the waterproof caps and grout overflow devices.

#534 - #536  From the WESTERN Bridge end.  Our questions concerning grouting the tendons have been answered. Evidently, after tensioning, waterproofing the tendons is of upmost importance in preventing RUST & the ultimate failure of said tendons - and possibly the structure. The equipment necessary to mix and pressure feed the grout into the tendon tubes is shown.

8/27/22: The Demise of Gray's Hill  -  Part 47
After two weeks, we thought it is time to again visit the New Bridge construction site.  GGG & MF
MF - 7/24/22 - 540 (click to see full vertical photo)
We've had, for a long time, two burning questions -- How will crews remove all the tons of False Work (HUGE STEEL & WOODEN beams) which supported the concrete bridge during construction?
MF - 7/24/22 - 541
What function do the 20 pictured machines fulfill?
MF - 8/27/22 - 542
Marc suggested that we first visit the Southern Hill which was, once, our entrance to Gray's Hill -- off Ridgecrest Rd. The following pictures were all taken from different levels on the pictured Southern Tall Hill and they answer the above questions.
MF - 8/27/22 - 543
See text below
NW view of bridge
#543-547: IN GENERAL -- A close look will reveal that the unknown Red & blue machines are some kind of "cable pullers". The four huge stacks of concrete blocks, which we named THE MOJAVE STONEHENGE, are actually counterweights.
Four "I" beams are placed crosswise under the bridge and attached to the eight (four on each side) "cable pullers". The beams are then raised up to hold the false work tightly against the underside of the deck and  the numerous HEAVY vertical supports are removed. The deck falsework can then be lowered to ground level & the job of false work removal can begin. Since this portion of the "false work" spans the heavily used BNSF Main Line, all trains must be halted & the tracks inspected before resumption of railroad traffic.

#554-555: The ten foot wide pedestrian/bicycle lane with the upright safety fence supports installed. The safety fence, evidently, will vary from 4.5 feet at both ends to 10.5 feet over the BNSF tracks--to dissuade JUMPERS & BOULDER DROPPERS---remember, this is California. The rebar to the right of the Bike lane is for a future barrier which will protect pedestrians/bike riders from high speed vehicles.

Last Sunday (Sept. 11), Marc & I again ventured to the new vehicular bridge over the BNSF transcon, at BNSF Cajon Sub MP 39.4.  The bridge is in the final construction phases.   MF & GGG

Marc is 5 feet 8 inches tall (68 inches) and the new railing is 54 inches which should give us a chance to do some train watching without railing interference.
# 569-570: Several have asked about RR photographic opportunities from the new bridge. Until now your question could not be answered because we didn't know the final height of the safety railing. Last edition, we could see the height of the safety rail supports but still did not know the height of the WIRE MESH INFILL PANELS. So today, with a few of the panels installed, we can safely report the following:
Marc is 5 feet 8 inches tall (68 inches) 
The shorter supports are 54 inches (including the 18" short concrete supporting wall).
Refer to pictures # 563-565: which show the number of 54 inch supports installed. Including BOTH SIDES of BOTH BRIDGE ENDS, approximately forty percent of the bridge will have the 54 inch high safety railing.

Marc has been traveling and camping through Texas for the last month and so Laura & I decided, Sunday, to drive over and see what's new with the bridge project.

As I've mentioned several times, the infrequent THUNDER storms here in the Desert are not to be ignored.  This newly named creek bed (Marc's Dry Creek Bed), and a few others, drain the entire area from the mountains (UPPER LEFT) down to the Mojave River (behind the camera). This Creek Bed flows under the Western Bridge approach (bridge shadow under mountains @ upper left), through the tubes in the BNSF ROW, across the top of Mojave Narrows Park and into the normally dry MOJAVE RIVER.
MF - 11/19/22 - 623

The Creek bed flow CAN become so intense that ALL erosion vulnerable areas must be protected with HEAVY plastic sheeting and RIP-RAP.

5/07/23: The Demise of Gray's Hill  -  Part 57

Great shot ... so whereabouts will you go to shoot the flyover now that Gray’s Hill is no more?
This question came from John P. after seeing the "South View" above.

Here is the reply from GGG:

There are still two good views of the flyover --- from the new bridge & from the NEW Ridgecrest RD. Neither have the prior elevation advantage(s) - but so be it.
If one does not mind a long hike up a near 45 degree loose dirt hill, the OLD ELEVATED view of the Flyover is still available from the peak between the old & new RidgeCrest Rds.
I've had a few questions concerning the disposition of all the Gray's Hill dirt removed during this construction ???
Much of the removed dirt from Gray's Hill has been used to elevate three large parcels of land directly South (2 miles) of the project, near Bear Valley RD. 
On the attached Google map, you will note Gray's Hill & the new bridge at the top and a large RED X at the bottom, near Bear Valley Rd. The RED X large land parcels were about the same level as the BNSF tracks & about 20-30 feet lower than RidgeCrest RD. For about 90 straight work days, large dump trucks carried Gray's Hill dirt South from the project to the low RED X area, eventually raising the entire elevation to near RidgeCrest Road level.  It appears to be a WIN WIN - in that the construction folks got rid of tons of unwanted dirt & the owner(s) of that previously low land, now have develop-able land.
In other words, Gray's Hill NORTH is now Gray's Flat SOUTH!!!   GGG

Finally, IT'S FINISHED !!!
Almost three years ago, Marc & I reported the first dirt being turned, to begin making the GreenTree BLVD/AVE/ROAD Extension a reality. On May 20, The City of Victorville hosted a Ribbon Cutting, Classic Car Show & Fun Walk to Celebrate the opening of the GREENTREE BLVD Extension. This major extension (road & bridge) will provide a third unimpeded crossing of the VERY BUSY BNSF railroad transcontinental Main Line. It will also ease routine and emergency traffic among the Cites of Apple Valley, Hesperia and Victorville.
Yesterday (May 20), Marc was busy elsewhere and so Jorge Lopez & I drove to what's left of Gray's hill to take the following images.

Many thanks to my friend and photographic partner Marc Fournier, for his many hours of climbing hills and dodging snakes to help bring you three years of GREENTREE EXTENSION construction documentation.
This photographic project would have been impossible without his help.
Also, our thanks to our friends  Doc Jones, Gordon G., Bob W., & Jorge L. for sharing their construction knowledge and answering many of our questions. 
We hope you have enjoyed our efforts
Gary & Marc
Who did ever expect there will be 672 photos on this one of a kind project ? Thanks to Gary and Marc ! Werner
