I-5 Skagit Bridge Collapse

Mount Vernon, WA – On May 23, 2013, a truck carrying an over-sized load struck several overhead support beams of the I-5 Skagit River Bridge causing an immediate collapse of the northernmost span. Three people in two different vehicles fell with the span. Fortunately they were rescued by boat and did not sustain serious injury.

The bridge collapse severed a vital transportation link between Vancouver, BC and Seattle, WA. Before the collapse, approximately 71,000 vehicles crossed the bridge every day. Replacing the collapsed span was a high priority.

Following the collapse, Pacific Pile & Marine crews were on-site surveying conditions of the levee on the north side of the bridge to establish safe access for positing a crane barge within the shallow region south of the existing bridge. In coordination with tow partner, Boyer Towing, PPM crews mobilized a crane barge carrying heavy cutting and lifting equipment to remove the debris including the steel truss and fallen vehicles. Work was overseen by the Washington State Department of Transportation and the National Transportation Safety Board. Click here to see photo.
