US 101/Hoquiam River-Riverside Ave Bridge - Machine Rooms Rehab

Project overview

This project replaces and repairs two machine rooms that help operate the US 101 Hoquiam River Riverside Bridge in Grays Harbor County.

Work includes repairs to the existing machine rooms and wall systems, removing the old machine room, and painting the operating room. To do this important preservation work, a large crane will lift materials, including new walls and a roofing system to the machine rooms on top of the bridge.

Spring 2023 - Summer 2023

$2 million

What to expect

During construction, the bridge will close nightly for up to eight consecutive nights. During the overnight work, travelers will follow a signed detour around the construction zone via local streets. We will share the dates of the night closures once they are confirmed by the contractor.

During the daytime, travelers may encounter intermittent lane and shoulder closures to allow crews to hoist up materials to the machine rooms above the roadway.

Rehabilitated machine rooms improve workplace safety for bridge crews and reduce unexpected lane closures due to electrical concerns.
