Due to the severity of the winter storm, the Pennsylvania Department of Transportation is temporarily reducing the speed limit on several roadways in the region.

PennDOT is urging motorists to avoid unnecessary travel but those who must head out will see speeds reduced to 45 mph on the following highways:

Interstates 78, 80, and 380;

U.S. 22 and 209; and

State Routes 33 and 248.

Although PennDOT crews have been treating roadways, the department’s primary goal is to keep roads passable, not completely free of ice and snow. PennDOT will continue to treat roadways throughout the storm until precipitation stops and roads are clear.

While PennDOT recommends not traveling during winter storms, motorists can check conditions on more than 40,000 roadway miles, including color-coded winter conditions on 2,900 miles, by visiting www.511PA.com. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 825 traffic cameras.

511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following regional Twitter alerts accessible on the 511PA website.
