The Interstate 5 Skagit River Bridge collapsed May 23, 2013 after an oversized load hit the bridge's trusses.

MOUNT VERNON, Wash. - Officials with the Washington Transportation Department said Saturday morning the department has changed the detour routes around the collapsed Skagit River bridge in Mount Vernon. 

Due to the collapse, Interstate 5 is closed between State Route 538 (College Way) in Mount Vernon and George Hopper Road.

WSDOT officials told KIRO 7 Eyewitness News that they will be updating their site for the latest changes on detour routes.

Transportation officials said drivers can expect delays in both directions. 

About 71,000 vehicles use that stretch of highway every day. The bridge is about 60 miles north of Seattle and 40 miles south of the Canada border. 

Memorial Day weekend could bring more drivers onto the roads, but drivers are urged to avoid the area. 

An investigation into the collapse is being handled by the National Transportation Safety Board. KIRO 7 Eyewitness News reporter Frank Field spoke with Chairman Deborah Hersman about the latest update.

“I think it’s really important to make sure we gather all the facts before we determine a cause here on scene. We have a full day ahead of us. We’re going to interviewing the truck driver, pouring through documents, records, maintenance information and getting in a boat and doing an inspection on the dropped span,” said Hersman.
