The bridge that collapsed along Washington State’s Interstate 5—sending three people plunging toward the Skagit River—was caused by a tractor-trailer, officials said Friday. The truck was allegedly carrying a load too tall for the bridge when it hit an overhead girder, sending a large part of the bridge into the water. All three of the victims sustained only minor injuries. In one of the cars sent overboard, Dan Sligh recalls thinking “hold on as tight as you can” before hitting the water. Sligh and his wife were en route to a camping trip in their pickup truck.
