Peter Western Bridge Replacement
Emergency Replacement of Peter Western Bridge
Location: The 2200 block of S 116th Street (between Military Rd and 24th Ave S).
Brief 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.
- Demolition is complete
- Staff is working with agencies to secure after-construction permits as required by law
- Design of a new bridge has begun
- Early work includes surveying and drilling for the purposes of soils investigation to determine foundation types
Project completion date is dependent on requirements from environmental permits.
