Status

Spring 2014


  • This project is complete.
  • Crews installed and opened the new span on Sept 15, 2013.
  • Watch video of the span swap.
  • Crews installed the girders for the new span the week of Aug. 12. 

Crews installed temporary spans and reopened the bridge to traffic on Wednesday, June 19 - less than four weeks after an incident involving an oversize load caused a portion of the bridge to collapse.

Now crews have completed building a permanent span, which was installed Sept 15.

On May 23, 2013, a portion of the bridge collapsed into the Skagit River near Mount Vernon after being struck by an oversize load. More than 71,000 drivers use this stretch of I-5 each day.

Why is WSDOT replacing a portion of the I-5 Skagit River Bridge?
WSDOT replaced the section of the bridge that collapsed to restore restore traffic to normal highway speeds across the river. 

Max J. Kuney Construction of Spokane was awarded the contract June 18, 2013 to build the permanent span for the bridge. The total current cost of the project is $8.5 million.

The contractual deadline to open the new permanent span to traffic was October 1.

The End Result
With construction complete on the permanent span, drivers can travel I-5 over the Skagit River between Burlington and Mount Vernon at normal highway speeds.
