A Pittsburgh bridge collapse has left 4 hospitalized and 10 injured at Frick Park early Friday morning, according to the Pittsburgh Post-Gazette

The injured were transported to the hospital with non-life threatening injuries. First responders reported to the scene and rappelled nearly 150 feet to help passengers from a dangling bus, while others formed a human chain to help rescuers with the effort. 

Pittsburgh Fire Chief Darryl Jones said rescue units remained on the site to assure there were no victims under the bridge during the collapse. Jones added that the gas leak caused by the collapse is now "under control." Families who were told to evacuate during the leak have returned home and their gas has been restored.

In Pittsburgh, the president looks to tout his $1 trillion infrastructure bill as well as his administration's economic progress in his first year. Pittsburgh Mayor Ed Gainey emphasized the importance of Biden's visit given the recent tragedy. 

"We know we have bridges we need to take care of. For him coming today to talk about why this funding is so important…this is critical we get this funding," Gainey told WITF.

Two of Pennsylvania's top Democrats, Josh Fetterman, the state’s lieutenant governor, who is running for Senate, and gubernatorial candidate Josh Shapiro, the state’s attorney general, will miss the president's visit because of scheduling conflicts.
