On Thursday evening, a section of the Skagit Bridge in Washington collapsed, dropping cars and passengers into the river below. There were no fatalities.
The bridge was built in the 1950s, but according to authorities, an 18-wheeler striking part of the bridge over the weekend may have weakened it, leading to the collapse. A 2010 evaluation by the Federal Highway Association listed the bridge as "Functionally Obsolete."
