Where is the longest toll road in the United States? (name and location)

Mount Equinox Skyline Drive
Vermont

Construction of Skyline drive began in 1941, but was suspended because of the war until 1947, when it was completed. Today it remains as the longest, privately owned, paved toll road in the United States.

Currently the longest "tollroad" by this we're considering limited access highways as there is no pre-defined handicap... is the Florida Turnpike... If you were to consider the Tri-state Turnpike (Indiana, Ohio, Pennsylvania) as one system then it would EASILY be the longest but they're owned by separate entities although they remain tolled.

Florida's Turnpike is slight over 300 miles in length and costs around $25 to drive its entire length.

The Governor Thomas E. Dewey Thruway is one of the longest toll highway systems in the United States. As a user-fee supported system, the Authority receives no State tax dollars, and is paid for by the travelers who use it.
