Welcome to Skagit County
May 5, 2026 Weekday Overnight Closures Scheduled for Marblemount BridgeThe Marblemount bridge on Cascade River Road will be closed to all traffic overnight, Monday evening through Friday morning, 8:00 p.m. - 4:00 a.m., from June 1st - June 19th due to ongoing construction efforts to rehabilitate the aging bridge infrastructure. There will be ongoing work on the bridge during daytime hours as well, but the road will reopen each day and every weekend for normal traffic. With the road washout over Jordan Creek on Rockport Cascade Road this past December due to the flood event, the closure of the Marblemount bridge means visitors and residents east of the bridge will be cut off from accessing State Route 20. First responders will still be able to access the area if an emergency occurs during the closures. Skagit County Public Works contracted with Stellar J Corporation in the spring of 2025 to complete a repair and maintenance overhaul project for the Marblemount bridge. The bridge is over 90 years old and was 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.
