[VIDEO]: Bridge Replaced in 57-Hour Timelapse

[VIDEO]: Bridge Replaced in 57-Hour Timelapse

Some people get a lot done over the weekend. Like the crew replacing the Route 30 Bridge over Bessemer Avenue last May. In just 57 hours, the crew disassembled and replaced the bridge in East Pittsburgh (Allegheny County). The original structure was from the 1930s and was replaced in record time thanks to the use of precast modules. Approximately 22,000 vehicles travel this particular stretch of Route 30, so the replacement had to be done quickly.

The bridge was designed by HNTB and the project contractor was Brayman Construction. The modular pieces created included concrete abutment caps, modular deck beams, and precast concrete approach slabs. The entire process can be seen in just under 7 minutes in this time lapse video. The crew doesn’t even let bad weather stop them — but you can see the rain all over the camera lens.
