Hoquiam: Detour route planned for US 101 Simpson Avenue Bridge repairs July 21-23

HOQUIAM – Upcoming work on the US 101 Simpson Avenue Bridge requires a two-day, around-the-clock closure.

Starting at 9 a.m. Tuesday, July 21, the one-way bridge, which carries traffic heading from Hoquiam to Aberdeen, will close to all travelers. It will remain closed until 9 a.m. Thursday, July 23.

During the closure, the nearby US 101 Riverside Bridge, which carries one-way traffic in the opposite direction, will be reconfigured to two-way travel. Travelers can expect congestion while the detour is in place. People are encouraged to add more travel time to help prevent delays.

About the work

Washington State Department of Transportation bridge crews will remove the aging wood piling that supports the west approach of the bridge. It will be replaced with a new steel structure. During the replacement, WSDOT maintenance teams will also make repairs to the driving surface of the bridge.
