21-23 SWR Regionwide Bridges Concrete Deck Patching

Project overview

Between summer 2022 and 2023, WSDOT's contractor, Granite Construction Company, will begin work on this pilot program to rehabilitate the concrete decks of several bridges throughout southwest Washington. Crews will remove all non-cement patches and replace them with cement material, extending the useful life of the bridges until future bridge deck rehabilitation projects can fully address each bridge structures individual needs.

Summer 2022 - Fall 2023
Project status
The cost of this project is estimated at approximately $3.8 million

What to expect

Starting June 5, contractor crews will return to the Cowlitz River Bridge at milepost 59, near Vader, to complete bridge deck patching work along the northbound and southbound bridge spans.

To facilitate the necessary repairs, traffic will be reduced to a single lane, around-the-clock, during the following times:

  • Northbound I-5: 8 p.m. Monday, June 5, through 10 a.m. Friday, June 9
  • Southbound I-5: 8 p.m. Monday, June 12 through 10 a.m. Friday, June 16 - The on-ramp from State Route 506 to southbound I-5 will be closed continuously during this time.

Travelers should anticipate significant delays of more than 30 minutes in the morning and up to an hour during peak afternoon travel times.

Ahead of the lane closures, travelers will follow advanced directional signs guiding them to begin shifting from two lanes of traffic down to a single lane. For everyone’s safety, the speed limit will be reduced from 70 mph to 55 mph through the work zone.

In summer 2022, Granite Construction Company will rehabilitate the concrete decks of several bridges throughout the Southwest Region and one bridge in South Central Region by patching. The intention is to remove all non-cementitious patches and replace them with new cementitious material, extending the life of the bridge structures until future deck rehabilitation projects can better address each bridge’s individual needs.
