​Due to the severity of the forecasted winter storm, the Pennsylvania Department of Transportation is anticipating temporarily restricting certain vehicles on entire length of Interstates 86 and 90 in Erie County.

Tier 3 of the commonwealth’s weather event vehicle restriction plan is expected to be put into place starting at 8 p.m. today.

On roadways with Tier 3 restrictions in place, no commercial vehicles are permitted except loaded single trailers and/or loaded enclosed cargo delivery/box trucks with chains or approved Alternate Traction Devices. Additionally, all school buses, commercial buses, motor coaches, motorcycles, RVs/motorhomes and passenger vehicles (cars, SUVs, pickup trucks, etc.) towing trailers are not permitted on affected roadways while restrictions are in place.

Speed limits will be restricted to 45 mph on these roadways for all vehicles while the vehicle restrictions are in place, and commercial vehicles not affected by the restrictions must move to the right lane.

Interstate 90 eastbound remains closed to all traffic from the I-86 interchange to the New York state line in connection with closures in New York.

The purpose of the restriction is to help ensure the interstates remain open during the most challenging conditions of the winter storm. When conditions improve, PennDOT will remove the travel restrictions.

Restrictions will be communicated via variable message boards, the 511PA traveler information website at www.511PA.com and smartphone apps. Motorists can also sign up for alerts on the website.

Although PennDOT crews are 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.

Motorists can check conditions on major roadways 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 1,000 traffic cameras.
