I-5 - Nisqually River Bridges - Bridge Painting


April 2014

  • Most of the painting work is complete on both the northbound and southbound I-5 bridges spanning the Nisqually River. 

This project cleaned and painted the steel framework of both Nisqually River bridges on I-5 in Thurston county. The fresh coat of paint will help prevent future corrosion to the steel, preserve the bridges' structural integrity, and prolong the life of the bridges.

Why is WSDOT painting the Nisqually River Bridges?
The Nisqually River bridges were last painted 25 years ago in 1988. Since then, the protective coating on the bridges deteriorated, exposing the steel to the weather and elements, which resulted in rust and corrosion. Painting the bridges preserved and restored the bridges' structural integrity and will protect the steel from future corrosion. 

The End Result
The steel framework of the bridges was cleaned and repainted with a protective coating. The project will prolong the life of the bridges for the 111,000 drivers who cross over them daily.

Project Benefits
This project helps prevent future corrosion and preserves the bridges' structural integrity. 

All work to remove the existing paint and apply new paint was done under full containment to protect the environment.
