I-5 - Skagit River Bridge Replacement - Emergency Repair

Temporary spans

The northern span of the I-5 Skagit River Bridge collapsed into the river on May 23, 2013, after an over-height load struck it. The collapse closed both directions of I-5 at the Skagit River. More than 71,000 drivers use this stretch of I-5 each day.

During the closure, traffic was rerouted through Mount Vernon and Burlington, adding significant travel time for those who use the only north-south interstate in that area. This had a major effect on all drivers, the economy and freight haulers.

Under an emergency contract, WSDOT worked with Atkinson Construction to remove the collapsed span from the river and install temporary spans to restore the interstate for most traffic. The temporary spans opened June 19, 2013, with reduced speed and weight limits, requiring many large loads to continue using detours until the permanent replacement span opened on Sept. 15, 2013.
