This page within the docuvision2020 website is a new blog that features the Barton Road Pedestrian Bridge (BRPB) construction. The bridge will link Parking Structure P4 on the south side of Barton Road to an Elevator Tower (presently under construction) on the north side of Barton Road near the southeast corner of the existing Children’s Hospital on the Dennis and Carol Troesh Medical Campus at Loma Linda University in Loma Linda, California. This project, benefiting patients, staff, and the general public, is a significant undertaking, which has been in the discussion and planning phases for many years.

Current Status as of December 13, 2021
Work continues on the elevator tower. A crew is preparing the exterior for the three-step stucco process. Inside the elevator tower, Otis elevator is installing the structural steel that will support the elevator cars. The rebar has been installed on the landing stairs and the bridge walkway surface. If the weather cooperates, the four-inch concrete will be poured for the walkway surface on December 15, 2021. A crew from the company that will be installing the metal side panels and the roof is currently anchoring the support embeds which will hold the metal roof columns. According to the on-site supervisor, the crews have been instructed to keep moving forward.
About the Layout of this Blog
The BRPB images featured in the Dennis and Carol Troesh Medical Campus construction blog (the principal docuvision2020 blog) will remain in that blog. However, to keep the construction of the BRPB in context on this page, those images will flow onto this page. With few exceptions, I will post the photos in descending order by date. The images from August 13, 2021, until completion, will not be posted on the hospital page. THEY WILL ONLY BE POSTED ON THIS PAGE!
December 15, 2021 – The Walking Surface Concrete Pour
The concrete crew at work on the north side of the BRPB over the fire lane.The BRPB is viewed from the third floor of parking structure P4. The phot was taken at approximately 8:05 AM with the temperature in the upper 30s to low 40s. By the time the photo was taken approximately three quarters of the walking surface concrete had been poured. I was unable to take a photo from the elevator tower second floor landing since a crew was cleaning the steps in preparation of the concrete pour.From the fire lane a view of the concrete pumping trucks and snorkle. After the crew works down the bridge, they will finish with the stair landings and stairs.
December 13, 2021 – UPDATE
A crew begins to install the metal ribbing for the stucco exterior which will cover the Elevator Tower.From the second floor landing facing south toward Parking Structure P4. The flooring rebar has been installed on the bridge and if all goes well the four-inch concrete flooring will be poured on Wednesday, December 15, 2021.Facing north from the third floor of parking structure P4. Notice the rebar and the electrical conduit, which will be covered with concrete. Two tradesmen are installing the supporting embeds on the east wall of the bridge.
November 12, 2021 – UPDATE
Thank you for continuing to visit the website. We’re back online again. Unfortunately, the site has had its hiccups of late. Hopefully, Hostgator has the problem resolved. I have been visiting the construction site and taking photos and I will be posting the most interesting images over this weekend. With the columns finished, the construction crew has been concentrating on the elevator tower, hanging steel, and installing the stairs in preparation for the beams to arrive. NOTE: ON NOVEMBER 22 – 24 BARTON ROAD WILL BE CLOSED TO TRAFFIC AT CAMPUS STREET AND ANDERSON STREET. On those dates, heavy cranes will be on-site to install the beams that will cross over Barton Road. This should be an exciting event!
November 24, 2021 – The Bridge Build, The Day After
From P4: The day after the build a crew is already working on the bridge: stabilizing and preparing the base for a four-inch concrete floor. When completed the bridge will have a roof with protective siding. Note the elevator tower at the north end of the bridge.
November 23, 2021 – The Bridge Build Continues
Just a Little After 8:00 AM: At the center-right, the first bean to go over the westbound lanes of Barton Road is lifted off the flatbed.A closer view of the first beam that will span the westbound lanes as it is picked from the low bed transport.Hovering over the columns above the westbound lanes.The contractor’s site engineer and drone operator use the drone to keep an eye, from above, on the beams as they are set in place.Just prior to setting the beam a crew on each end, scribes and guides the beam toward the landing points. Once the beam has been set, they also release the crane’s cable.The beam over the westbound traffic lanes rests on the columns.At the center, the first prestressed concrete plank is hoisted toward the beams over the fire lane.The beam is free of the cables. Note the first prestressed plank (upper center right), which be lowered between the two beams over the fire lane.The first prestessed plank is carefully lowered toward the two beams over the frontage road.The first prestresssed concrete plank is lowered between the two beams.The second beam (center left) which will span the westbound lanes is rolled into position. The first beam over the westbound lanes has been set.The scope of the project from the median to the elevator towers is viewed from the 6th floor of P4.The second beam to span the westbound lanes is slowly swung into place.The second beam over the westbound lanes is slowly being positioned.The second beam over the westbound lanes is set.

November 22, 2021 – The Bridge Build Begins
Prior to the heavy lifting, the crew meets for a safety/sequencing meeting to make sure everyone is on the same page.Before the hoisting began, I checked Parking Structure P4 to see if my friend Wibert was watching. He didn’t disappoint me, there he was (right) explaining something to an unidentified viewer. Wilbert, who is in his mid-80s comes to P4 almost daily to check out the project.The first beam weighing 85,000 pounds is rolled into place.The beam is about to be lifted from the flatbed and trailer.The beam is lifted off of the flatbed.Slowly the beam rises higher above the truck bed. As the beam rises, the crane operator must keep the power lines as well as the steel on the second floor landing in mind as the beam is brought closer to the column caps.The beam is nearing the optimum position above the column caps.Inches from the column caps on both ends.The beam rests on the column caps.The placed beam as viewed from the sixth floor of P4.The lift of the second beam begins.The second beam: This is where the crane operator has to use great care as he lifts the beam over the first beam.The second beam is within a foot of both ends of the column caps.The two beams now span over the frontage road that parallels Barton Road.The pedestrian bridge beams connect to the second-floor landing span over the frontage road.

Elevator Tower East Elevation: The concrete block of the elevator tower. The two openings are for the elevator doors that will open to the east, which will allow access to the new hospital as well as the emergency departments. Elevator Tower West Elevation: The two elevator doors on the west side open to the landing that is closest to the existing Children’s Hospital.Elevator Tower East Elevation Facing South: From this angle, we see the blocks of the elevator tower and the bridge columns, which are being formed for the concrete horizontal beams.

While sitting on the driveway, hunkered against the southwest retaining wall below the new Children’s Emergency Department’s parking lot, I was able to capture the helicopter coming in for a landing on the south heliport above the Children’s Hospital. A framer was working high on a column form below (lower center right) and didn’t miss a hammer stroke. The safety officer of the project standing next to me mumbled: “I can’t get enough of those helicopters, the guy on the tower, seen one seen them all.” Framer working on the forms for one of the columns that will support the elevator lobby.The framers are working on the support columns for the elevator lobby. It is their hope to have a concrete pour on Wednesday (08.18.21).
