Bridge painting preserves the overall integrity of the structure and is more cost-effective than replacement. Steel truss bridges need to be regularly cleaned and painted to preserve their integrity and keep them in good working condition. The paint on the I-5 Cowlitz River Bridges is cracked, corroded, and peeling in places. Areas of rust are also visible. Once repainted, the bridges will be protected from weathering and deterioration, extending the useful lifespan of these structures. Left unpainted, the steel trusses would eventually deteriorate from rust.
How will the work be done?
What can travelers expect during construction?
WSDOT will work to keep people moving and minimize delays whenever possible. During construction, travelers will encounter intermittent nighttime single-lane closures on north and southbound I-5 over the Cowlitz River Bridges near Vader in Lewis County. There will be construction noise at night & during the day. Intermittent closures of the State Route 506 on-ramp to southbound I-5 will also be needed during construction.
Travelers should expect delays of up to 20 minutes, for additional intermittent, nighttime single-lane closures. This project is not expected to have impacts to river traffic. Construction is scheduled for completion in summer 2022.
