Ten people were injured and three were taken to a hospital after a snow-covered bridge in Pittsburgh collapsed Friday morning, Pittsburgh fire officials said. The three people taken to the hospital have non-life-threatening injuries, Pittsburgh Fire Chief Darryl Jones told reporters Friday. He said three or four vehicles were on the bridge when it collapsed. Pittsburgh Port Authority confirmed to USA TODAY that a 60-foot city bus was on the bridge during the collapse. The bus driver and two passengers escaped without injury. A "massive gas leak" caused by the collapse is now "under control" and gas services have been restored. A gas line was cut after the public safety department reported "a strong smell of natural gas in the area." Officials have urged residents to avoid the area, and several area families were evacuated but have since returned to their homes surrounding the bridge.
