Best Project, Highway/Bridge: The West Seattle Corridor Bridge Rehabilitation and Strengthening (WSCBRS) Project
As one of three bridges that connect the West Seattle Peninsula to the rest of the city, the $64-million West Seattle High-Rise Bridge (WSHB) is a critical piece of infrastructure because the next available access point is more than four miles south of Seattle. More than 125,000 commuters rely on the bridge to cross the Duwamish River into downtown.
After a routine inspection discovered structural cracking in March 2020, the bridge was immediately closed and stabilized. To do this, the WSP team used large steel weldment post-tensioning anchors located in the middle of the bottom slab.
