I-5 Skagit River Bridge Emergency Replacement
In May 2013, span 8 of the I-5 Skagit River Bridge collapsed when an oversized load struck the steel truss. Washington State Department of Transportation (WSDOT) awarded Atkinson the contract for the emergency replacement project.
The I-5 Skagit River Bridge Emergency Replacement contract was limited to “pre-approved” contractors. Due to Atkinson’s previous success on WSDOT projects, the company was one of three pre-approved emergency contractors eligible to construct the replacement bridge.
Atkinson removed the debris from the Skagit River, repaired damage to the remaining bridge spans, and installed a temporary replacement. The temporary replacement section for the I-5 bridge over the Skagit River carries two lanes in each direction. The team installed two 160-foot Acrow structural steel Bailey bridge spans. The connection was paved, striped, and equipped with new reduced speed limit signs.
Atkinson completed the bridge replacement in just 30 days.
