Three people were rescued from a river after a bridge along Interstate-5 in Washington State collapsed on Thursday evening, plunging two cars into the water below, according to Washington State Patrol.
The extent of the injuries for the three is unclear, but all were evaluated on scene and were being transported to area hospitals, according to Marcus Deyerin of the Washington Incident Management Team. Authorities say they have no reason to believe any others are still in the river.
Two vehicles were submerged in the Skagit River when the bridge fell around 7 p.m. local time, and traffic has been closed in both directions.
NBC Seattle affiliate KING5 reported that traffic was significantly backed up in both directions. I-5 is the main freeway that runs along the West Coast.
The bridge was built in 1955 and was listed as "structurally obsolete" by the National Bridge Inventory in its most recent assessment. In a 2010 evaluation, the group said the bridge is "somewhat better than minimum adequacy to tolerate being left in place as is."
However the bridge did not make the Washington Department of Transportation's list of "structurally deficient bridges."
