BNSF 8-9-2019 Network Update
First BNSF train crossing new bridge in Home Valley, Wash. – August 5, 2019
BNSF engineering crews were also active on the Fallbridge Subdivision as a new bridge was placed into service on Monday over the Wind River in Home Valley, Washington. Rather than being constructed on site, the new bridge span was transported by barge more than 60 miles down the Columbia River from Portland. Disruptions due to the 36-hour work window required to install the new span were minimized by utilizing alternate routes for some traffic.
This completed project, which included another bridge replaced approximately 10 miles west on the subdivision back in June, is part of BNSF’s Bridge Maintenance Program. Under the program, bridges across the network are replaced based on their condition and as they near the end of their useful life. With 13,000 bridges on our network, BNSF conducts comprehensive inspections and significant maintenance work throughout the year to ensure that each bridge remains safe, secure and structurally sound.

| I hope ACC doesn't break this BNSF project link because it contains a scroll through a lot of neat construction photos. This photo is one of them. They are floating out the old span. The new span waits in the background. |
Hey! I was the project engineer with BNSF on this project. I just stumbled across your post. This was a very fun project, and I'd be happy to answer any questions you might have.
ReplyDeleteSo you are Luke Sykora, one of the narrators of the video? Thanks to the video and the Network Update, many of my questions are answered. I'm left with: what was the speed limit before and after the replacement and the weight limit for the new bridge? I'm guessing 315,000 lb. I like railroad bridges because truss spans get replaced with truss spans rather than slabs of concrete. I was going to ask about other videos, but I believe I have found them.

I have already studied the Salmon Bay bridge.

I'll have to study the Washougal bridge.
The video mentioned that five other pin-connected trusses were replaced in 2019. Do you know of documentation on the others?
In this case, the views of the new span going up the river were of special interest. In fact, I just remembered to add the "towboat" label to these notes.
What else have you worked on and what are working on now?
Hi, may i know the cost of this bridge...If there is a reference about it it will be appreciated... Thanks

ReplyDeleteI've written everything I know about this project. If you find a cost, please share in a comment.
DeleteActually I read it yesterday but I had some thoughts about it and today I wanted to read it again because it is very well written. guy wire inspection
