While the vast majority of Interstate highways have no tolls, approximately 2,900 miles of Interstates are tolled in 21 states. These tolled facilities range in length from 500-mile New York State Thruway to tolled sections of I-95 in Delaware and Maryland.
The longest interstates in the U.S. are ones that go coast-to-coast and end in zeros. Interstate 90 connects Boston to Seattle and is more than 3,000 miles long. Interstate 80, which runs from just west of New York City to San Francisco is next, and Interstates 40 (Wilmington, NC to Barstow, CA) and 10 (Jacksonville, FL to Santa Monica, CA) are also among the longest.
