The Washington State Department of Transportation is warning anyone who plans to travel across the Simpson Avenue Bridge in Hoquiam to plan for extra time next week. 

Starting 8 a.m. Monday, May 10, bridge maintenance crews will examine the structure using a special under-bridge inspection truck. 

This work requires crews to close the bridge to travelers for safety.

Bridge closure details

  • Beginning 8 a.m. Monday and Tuesday, May 10-11 until 2 p.m. each day, the bridge will completely close to all travelers. A signed detour will direct eastbound travelers to the US 101 Hoquiam River Riverside Bridge, where two-way travel will be temporarily allowed to accommodate the inspection.
