January 19, 2024

OIL CITY, Pa. – Due to the severity of the winter storm, PennDOT is temporarily reducing the speed limit on Interstates 79, 86, and 90 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:

I-79 from Exit 166 (Route 6N – Albion/Edinboro) to the end of I-79;

I-86 from the beginning of I-86 to the New York state line; and

I-90 from the Ohio state line to the New York state line.

The following restrictions also remain in effect today in the Northwest Region in accordance with the commonwealth’s weather event vehicle restriction plan:

Interstate 79:

Tier 2 vehicle restriction from the I-80 interchange in Mercer County to the West Virginia state border.

45 mph speed reduction with commercial vehicles not covered by the Tier 2 restriction allowed in the right lane only from the I-80 interchange in Mercer County to Exit 77 (Interstate 76/Turnpike – Youngstown, Ohio/Harrisburg).

Interstate 80:

Tier 1 vehicle restriction from the Ohio state border to the New Jersey state border.

45 mph speed reduction with commercial vehicles not covered by the Tier 1 restriction allowed in the right lane only from the Ohio state border in Mercer County to the New Jersey state border.

The purpose of the restrictions 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.
