PITTSBURGH (KDKA)- A quick snow storm overnight led to some slippery conditions around town.

Those slick roads led to a couple of accidents early Thursday morning.

In Wilkinsburg, a car lost control on Penn Avenue and slammed into a pole. The crash happened around 1:30 a.m.

Three men in the car were trapped inside. One man was able to exit the car by himself. It took crews about 90 minutes to remove all of the men from the car.

They were all transported to a local hospital for treatment.

In Richland Township, a vehicle lost control along Route 910 near Clearview Road.  The crash happened just after midnight.

Police say the vehicle went over a hillside. One man was inside the car and was reportedly bleeding from the head.

Crews shut down Route 910 between Babcock Blvd. and Route 8 while they investigated the crash.

Around 2:30 a.m., a woman was hit by a car in Uptown. She was walking along Fifth Avenue near Gist Street when a vehicle hit her. The woman was transported to the hospital, but she was alert and conscious when medics took her away.

Police are investigating.

Flakes flew along the interstates and salt trucks were there and on side streets spreading materials.

The problem is with temperatures dipping, the salt doesn’t melt the same way.

“Salt starts to lose its effectiveness at a certain temperature – in the teens normally. What we’ll be doing tonight is mixing anti-skid material in with that salt,” PennDOT’s Steve Cowan said.

The good news is salt supplies for PennDOT and for the City of Pittsburgh are plentiful this year compared to last.

In the city, you can dial 311 to let crews know about the places that need to be treated.

PennDOT says you can dial 1-800-FIX-ROAD to let them know about the icy spots.
