    PennDOT Places Speed Limit Restrictions on Interstates in Erie County

    January 02, 2026

    Due to the winter weather impacting the region, the Pennsylvania Department of Transportation (PennDOT) is temporarily reducing the speed limit on interstates in Erie County.

    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:

    • Interstate 79 from the Interstate 90 interchange to the end point.  
    • Interstate 86 from the Interstate 90 interchange to the New York state line.
    • Interstate 90 from the Interstate 79 interchange to the New York state line.

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

    Although PennDOT crews have been treating roadways, the department’s primary goal is to keep roads passable, and they will 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 1,200 traffic cameras. 

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

    Motorists should always allow plenty of space when driving near plow trucks. Also, for their own safety and the safety of plow operators, motorists should never attempt to pass a truck while it is plowing or spreading winter materials.
