I-5 - SB Toutle River Bridge - Expansion Joint, Deck Repair and Overlay - Complete October 2019

Project news

In summer 2019, Washington State Department of Transportation contractors, M.J. Hughes Construction, Inc., began work to resurface the bridge deck along the southbound span of the Toutle River Bridge between mileposts 51.48 and 51.95, on Interstate 5, just north of Castle Rock, in Cowlitz County.   

Originally built in 1969, the Toutle River Bridge deck surface was showing it's age and was in need of repair. Over time, a combination of heavy traffic and weather conditions caused the bridge deck surface to deteriorate, resulting in cracks and rutting in the pavement. Resurfacing work helped to preserve the integrity of the bridge deck, extending the life of the bridge, and providing a smooth and safe connection for all travelers along I-5.
