Interstate Highway Act

Tollways

Many limited-access toll highways that had been built before the Interstate Highway Act were incorporated into the Interstate system (for example, the Ohio Turnpike carries portions of Interstate 76 (I-76), I-80, and I-90). For major turnpikes in New York, New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Kansas, Oklahoma, Massachusetts, New Hampshire, Maine, and West Virginia, tolls continue to be collected, even though the turnpikes have long since been paid for. The money collected is used for highway maintenance, turnpike improvement projects, and states' general funds. (That is not the case in Massachusetts, where the state constitution requires the money be used for transportation.) In addition, there are several major toll bridges and toll tunnels included in the Interstate system, including four bridges in the San Francisco Bay Area, ones linking Delaware with New Jersey, New Jersey with New York, New Jersey with Pennsylvania, the Upper and Lower peninsulas of Michigan, and Indiana and Kentucky in the Louisville area. Tolls collected on Interstate Highways remain on segments of I-95, I-94, I-90, I-88, I-87, I-80, I-77, I-76, I-70, I-64, I-44, I-35, I-294, I-355, and several others.
