MOUNT VERNON, WA - A truck hauling an oversized load of drilling equipment hit an overhead bridge girder on the major interstate between Seattle and Canada, sending a section of the span into a river below as the driver watched the structure collapse in his rearview mirror.
Two other vehicles plunged into the Skagit River, but all three occupants escaped with only minor injuries.
The spectacular scene unfolded about 7 p.m. Thursday on the north section of the four-lane Interstate 5 bridge near Mount Vernon, about 60 miles north of Seattle and 40 miles south of the Canada border, and disrupted travel in both directions. Officials warned it could be weeks before things returned to normal along the heavily-travelled corridor.
