About Interstate 87
The New York State Thruway runs 331 miles from New York City to the Canadian border. Gas prices along I-87 are elevated throughout due to New York's high state fuel taxes of 47 cents per gallon.
The average gas price along Interstate 87's route today blends prices from all the states the highway passes through. This blended average reflects both high-price and low-price state markets along the full corridor.
Interstate 87 spans 1000 miles across multiple states. For a vehicle averaging 28 MPG highway, the fuel cost varies significantly depending on which states and price zones the route covers.
Interstate 87 passes through or near major cities where competitive fuel markets and warehouse clubs offer the best prices. Look for Costco, Sam's Club, or high-volume discount stations in each major metro along your route.
A 2-mile detour to save 20 cents per gallon on a 15-gallon fill-up saves $3. With a car getting 28 MPG, the detour uses 0.14 gallons. Detours above 3-4 miles for savings under 20 cents per gallon are generally not worthwhile.
