The southbound I-5 Stillaguamish River Bridge will have its deck replaced.

Overview
We replaced the 81-year-old deck of the southbound I-5 Stillaguamish River Bridge with new concrete and rebar. We also replaced some of the supporting structural steel. The original deck was worn out, with cracks, ruts and potholes that could no longer be repaired.

Replacing the bridge deck and repairing some of the steel supports allows the bridge to continue serving the region for at least another 50 years.

How You Benefit
Cross GlyphImproves Safety
Replacing the deck minimizes the chances of cracks or potholes. It improves drainage on the bridge, reducing standing water and improving safety for drivers.
Dollar Sign Glyph Economic Incentive
This project extends the life of the highway another 50 years. Replacing the deck and some of the structural steel reduces maintenance requirements and frees up crews for other work.

Partnerships & Cooperation
Throughout the process, WSDOT coordinated closely with the city of Arlington and the Stillaguamish Tribe.
