Peter Western Bridge Replacement

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 will occur in two phases. Phase 1 will demolish and remove the bridge, temporarily stabilize stormwater facilities and the streambed. Phase 2 will install a permanent replacement bridge, permanent stormwater facility repairs, and restore the streambed and adjoining ravine side slopes.

Project Status

Phase 1 Status

Phase 2 Status

  • Based on the current design progress, the bridge will be under construction in early 2019, and will open to traffic in the fall of 2020. This timeline assumes there are no issues in obtaining the necessary property rights to do the work.

Estimated project completion date: Project completion date is dependent on requirements from environmental permits.
