Peter Western Bridge Replacement

Updated December 16, 2020

Project Location

The 2200 block of S 116th Street (between Military Rd and 24th Ave S).

Project Overview

On February 9, 2017 City staff responded to a report of severe erosion occurring below the bridge. The bridge was closed for structural inspection, which revealed two bridge columns had been completely undermined. A third column was only partially supported. The bridge was declared structurally deficient. Burien applied for and has been awarded emergency funding to demolish and remove the existing structure; and to construct a replacement bridge, repair damaged stormwater facilities in the ravine, and restore the eroded streambed.

The project occurred in two phases. During Phase 1, the damaged bridge was demolished and removed and stormwater facilities and the streambed underneath the bridge were temporarily stabilized. During Phase 2, the permanent replacement bridge was installed, permanent stormwater facilities were repaired, and the streambed and adjoining ravine side slopes were restored.

Hamilton Construction Company was awarded through a competitive bid process the contract to construct the new bridge. The contract award was for $4.59 million. This does not include design, permits, and other associated costs. 

Project Status

The bridge opens to vehicle and pedestrian traffic on December 21, 2020. An opening celebration is scheduled for February 2021.
