Bridge deck preservation work begins next week throughout southwest Washington

Travelers should expect reduced speed limits through work zones

VANCOUVER – People embarking on end-of-summer road trips throughout southwest Washington will need to plan ahead as work to improve the surface of several bridges starts next week.  

On Monday, Aug. 8, the Washington State Department of Transportation’s contractor, Granite Construction, will begin work to remove asphalt bridge deck patches along several bridges and replace them with cement. This work will extend the useful life of the bridges and smooth the bridge deck surfaces, which will keep traffic moving until future bridge deck rehabilitation projects can fully address each bridge structure’s individual needs.

What can travelers expect

Once construction begins, travelers should expect around-the-clock single lane closures and temporary speed limit reductions of 25 mph along several outlying bridges and within the work zones. When flaggers or portable temporary traffic control signals are on site travelers may experience delays of up to 20 minutes.

Additionally, crews will have an around-the-clock single lane closure in place along both directions of the Interstate 5 Cowlitz River Bridges and a temporary speed limit reduction from 70 mph to 55 mph through the work zone. Extended single lane closures may be necessary and will occur from 8 p.m. Mondays through 10 a.m., Fridays, and will result in major traffic delays. Nighttime single lane closures may occur when extended closures are not in use.

The following bridges will be affected by this project:

  • State Route 14 Glade Creek Bridge between Mainline Road and Glade Creek
