The northbound SR 529 Snohomish River Bridge is closed at Marine View Drive in Everett because of an accident that damaged the bridge.

The impact of the SUV did significant structural damage to vertical and diagonal support beams, said Dave McCormick, assistant regional administrator for maintenance and operations. Without these support beams the deck could sag. The extent of damage is quite significant.

To bring the bridge into working order, crews have to replace the vertical and diagonal beams, replace about 30 feet of guardrail, and dig out and replace concrete that supports the guardrail.

Crews began moving a large crane into place and manufacturing the steel beams on Saturday afternoon.

We will position the crane below the bridge and use it as a work platform. We don t want to put any weight on that bridge, said McCormick.

The steel truss bridge was built in 1927. The DOT says on a typical weekday, the bridge carries 15,000 vehicles.

The connection is a key link between Everett and Marysville. A signed detour to northbound I-5 is in place and should add about 10 minutes to the typical northbound trip. The southbound lanes which are on a second, unconnected bridge remain open to traffic.

Crews hope to open the bridge to traffic by the Monday evening commute.

Repairs are estimated to be $30,000 and WSDOT s Rick Management group will pursue reimbursement through the vehicle owner s insurance company.
