A large section of the Interstate 5 bridge over the Skagit River in Washington state collapsed Thursday, sending two vehicles and three people into the water. The 1955-vintage bridge had been rated "functionally obsolete," according to the Federal Highway Administration. Just two days before the I-5 bridge went down, the Seattle chapter of ASCE gave Washington state's bridges a C- grade. The state engineer is investigating reports that a truck with an over-sized load may have hit the bridge prior to the collapse.
