Toll bridge

A toll bridge is a bridge over which traffic may pass upon payment of a toll, or fee.

History

The practice of collecting tolls on bridges harks back to the days of ferry crossings where people paid a fee to be ferried across stretches of water. As boats became impractical to carry large loads, ferry operators looked for new sources of revenue. Having built a bridge, they hoped to recoup their investment by charging tolls for people, animals, vehicles, and goods to cross it.

The original London Bridge across the river Thames opened as a toll bridge, but an accumulation of funds by the charitable trust that operated the bridge (Bridge House Estates) saw that the charges were dropped. Using interest on its capital assets, the trust now owns and runs all seven central London bridges at no cost to taxpayers or users.

In the United States, private ownership of toll bridges peaked in the mid-19th century, and by the turn of the 20th century most toll bridges were taken over by state highway departments. In some instances, a quasi-governmental authority was formed, and toll revenue bonds were issued to raise funds for construction and/or operation of the facility.
