PITTSBURGH (KDKA) — Heavy rains caused major problems north of Pittsburgh along McKnight Road, including a sinkhole.

Photos from Ray Feather show a massive sinkhole that has opened up near the Bed Bath and Beyond store on McKnight Road.

The sinkhole is next to the Waldorf Park apartments.

Heavy rains and flash flooding made for a dangerous and challenging Thursday morning commute across the area, and the rain is continuing to fall.

“It was intense,” said Brandy Peluso, who works at the Sports Clips on McKnight Road. “It looked like a river out front. People were trapped.”

McKnight Road has been closed between I-279 and Nelson Run Road, but most of the on-road damage from the storm has been cleaned up.

A fallen tree also shut down Babcock Boulevard as KDKA’s Brenda Waters followed a 9-1-1 call for a woman trapped in a building.

When KDKA arrived, the woman, who was pregnant, was rescued by John Crawford. He carried the woman out on his shoulders.

“The water was pretty high,” said Crawford, whose company owns the building. “When we pulled up in the parking lot, there was 6-8 inches of water.”

The morning storms came fast and furious with downpours, lightning, thunder and flooding.
