• CASCADE RIVER ROAD #97950 WILL WILL BE CLOSED  AT MILEPOST 0.03 (Marblemount Bridge) FROM SEPTEMBER 2-16, 2025

Stellar J Corporation will be conducting the first phase of a two-year repair and maintenance project on the Marblemount Bridge over the Skagit River. The over 90-year-old bridge requires these repairs to go back to two-lane operation, remove the current weight restrictions, and extend the life of the bridge.

The road will be closed to all vehicles, including emergency vehicles.

For the safety of all road users and workers, we ask the public to please respect the closure and its signage.

The Detour Route for this closure will be State Route 20, State Route 530, and Rockport Cascade Road, applicable to both directions. A graphic of the Detour Route can be found here.
