I-5 Skagit River Bridge emergency repair
Location: Mount Vernon
General contractor: Guy F. Atkinson Construction
Owner/developer: Washington State Department of Transportation
Primary designer: Washington State Department of Transportation
On May 23, 2013, a portion of the Skagit River Bridge collapsed after being struck at 7 p.m. by a truck, closing Interstate 5 the day before Memorial Day weekend.
At 11 p.m. the Washington State Department of Transportation contacted Atkinson Construction, requesting available project manager, construction manager and craft/equipment resources.
The next morning WSDOT awarded the project to Atkinson and the contract was signed on site. Atkinson immediately loaded barges with equipment and mobilized more than 75 craftsmen to the site.
Atkinson crews worked around the clock seven days a week to complete the job. Demolition began May 26, temporary bridge replacement parts began arriving May 27, crews completed demolition on June 7 and pier retrofits on June 10, all while erecting the modular Acrow Corp. bridge just north of the river.
By June 19, they installed, paved, striped and opened the temporary bridge less than four weeks after the collapse.
The project experienced zero recordable accidents or first-aid claims.
