Update: Date changes for Riverside Bridge overnight closures in Hoquiam

Timing for work on the Riverside Bridge in Hoquiam has been adjusted with new closure dates.

The Washington State Department of Transportation had said that overnight work on the bridge would cause closures starting June 15, but on the day officials announced the change.

The contractor working for the Washington State Department of Transportation updated the schedule.

Nighttime closures will now begin starting Tuesday, June 20 as crews will close the Riverside Bridge to traffic overnight, while upgrading the machine rooms that help operate the bridge.

The first overnight closure will start at 9 p.m. on Tuesday, June 20. 

During the closure, northbound US 101 travelers will follow the signed detour over the Simpson Avenue Bridge with a flagger alternating traffic one direction at a time through a single lane.
