Due to the winter storm, PennDOT is temporarily reducing the speed limit on?Interstate 380 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 Interstate 380.

On roadways with speed restrictions, commercial vehicles not affected by restrictions on these or other roadways must move to the right lane.

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.

Snow is expected to taper off through this evening.
