Within the U.S. state of Pennsylvania, Interstate 90 spans 46.4 miles (74.7 km), all within Erie County, from the Ohio border near West Springfield to the New York border near North East. I-90 is the primary east-west highway in the Erie area, passing south of downtown and interchanging with Interstate 79, which connects downtown Erie to southern Pennsylvania and beyond, and Interstate 86, linking Erie to the Southern Tier of New York. U.S. Route 20, which interchanges with I-90 near the New York-Pennsylvania border, parallels I-90 across the county.

While most of I-90 east of Illinois is part of a toll road, no portion of I-90 in Pennsylvania is tolled; however, I-90 becomes the tolled New York State Thruway upon entering New York.
