Barr Creek Bridge 158 Replacement


Barr Creek Bridge 158 is a short span bridge located south and east of the City of Monroe, near milepost 3.03 on Ben Howard Road. The existing bridge is a two span, 21-foot long structure originally built in 1956. The bridge is built on timber piles and needs to be updated to meet Seismic Design Codes. Barr Creek Bridge is considered a seismic lifeline route structure. Seismic lifeline routes are designated as essential to life safety services after seismic events.


Snohomish County plans topographic survey, hydraulic analysis and soil investigation work in 2018 to support scoping and design engineering of the replacement bridge. Snohomish County is currently seeking funding; a construction date has not been set.

Traffic Impacts

The planned geotechnical work should not impact traffic.
