    REVISED: PennDOT Lifts Vehicle Restrictions on Interstates 86 and 90 in Erie County; Tier 4 Vehicle Restriction Remains on Interstates 79, 80 and 376 in Northwest Region

    January 26, 2026

    Speed Reductions Remain in Place throughout the Northwest Region

    The Pennsylvania Department of Transportation (PennDOT) has lifted the temporary restriction on certain vehicles from traveling on Interstates 86 and 90 in Erie County

    A vehicle restriction reflecting Tier 4 of the commonwealth’s weather event vehicle restriction plan remains in place on Interstates 79, 80 and 376, as well as additional interstates across the Commonwealth.

    Speed limits remain restricted to 45 mph on these roadways for all vehicles, and commercial vehicles not affected by other roadway restrictions must move to the right lane on following interstates in the northwest region:

    • Interstate 79.
    • Interstate 80. 
    • Interstate 86.
    • Interstate 90.
    • Interstate 376.

    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.
