A snow-covered bridge in Pittsburgh collapsed Friday morning, just hours before President Joe Biden was expected to visit the city on a previously scheduled trip to discuss infrastructure.No fatalities have been reported, Pittsburgh Mayor Ed Gainey said in a news conference at the scene in the area of Forbes and Braddock avenues.There had been 10 “minor injuries,” Fire Chief Darryl Jones said, and three people were transported from the scene. None of the injuries were life-threatening, he said.

Four vehicles were on the bridge when it fell, Jones said. Teams are still performing reconnaissance to ensure no one was under the bridge when it collapsed, he said.

The cause of the collapse is under investigation, he said. The National Transportation Safety Board said it was sending a “go team” to the collapse, with an estimated arrival of Friday afternoon.

First responders used ropes to rappel down to get to the victims, Jones said. Crews also used what he called a “daisy chain” where they linked hands to reach the victims and pull them out.

In an interview with CNN, Pittsburgh City Councilmember Corey O’Connor said it was fortunate that the collapse didn’t happen later in the morning, when there likely would have been far more traffic on the bridge.

“If this would have occurred an hour later, this is a road that gets probably about 15,000 cars on it a day, and if it was rush hour, we would be looking at a couple hundred cars down in that valley,” he said. “We got very, very lucky today, and hopefully those individuals at the hospital recover quickly and they’re home safe in the next couple days.”

The Allegheny County Police Department was notified about a partial bridge collapse sometime after 6 a.m. on Friday, according to Amie Downs, a spokesperson for the county.

Only minor injuries have been reported, including the driver of an articulated bus and two passengers, Downs said.
