FOR IMMEDIATE RELEASE
Marblemount Bridge to Close for Two Weeks
The Marblemount bridge on Cascade River Road will be closed to all traffic, including emergency vehicles and pedestrians, from September 2, 2025, through September 16, 2025, due to ongoing construction efforts to rehabilitate the aging bridge infrastructure. An additional 15-day continuous bridge closure will take place during the 2026 construction season. There may be intermittent days when the bridge is closed to traffic during the span of the project as well, but only two extended closures are scheduled at this time.
Skagit County Public Works contracted this past spring with Stellar J Corporation [ [link removed] ] to complete a repair and maintenance overhaul project for the Marblemount bridge. The bridge is over 90 years old and is currently under a weight restriction and limited to one lane traffic. The bridge has a failing paint system, corrosion to truss elements and gusset plates, pack rust in many connections in the steel floor system, missing fasteners, leaking joints, and delaminated patches in the bridge deck. The maintenance project will extend the life of the bridge, return the structure to two lane traffic, and remove the load posting, while preserving its historical importance in the area.
The $18.5M project was fully funded through the 2022 Federal Highway Administration Local Bridge Program Selection, allocated via the Washington State Department of Transportation. The program funds bridge rehabilitation projects that are not under the federal aid system. Estimated completion of the project is fall of 2026.
