In summer 2022, 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.
What to expect
Once construction begins, travelers should expect around-the-clock single lane closures on the I-5 - Cowlitz River Bridges, and a temporary speed limit reduction from 70 mph to 55 mph, through the work zone. Nighttime single lane closures may occur when extended closures are not in use.
For the outlying bridge structures, once construction begins, travelers should expect significant delays with an around-the-clock, single-lane closure where permitted, and a temporary speed limit reduction to 25 mph throughout the work zones. When flaggers or portable temporary traffic control signals are on site travelers may experience delays of up to 20 minutes.

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.
