A transporter bridge, also known as a ferry bridge or aerial transfer bridge, is a type of movable bridge that carries a segment of roadway across a river. The gondola is slung from a tall span by wires or a metal frame. The design has been used to cross navigable rivers or other bodies of water, where there is a requirement for ship traffic to be able to pass. This has been a rare type of bridge, with fewer than two dozen built. There are just twelve that continue to be used today, including one converted into a lift bridge and one designed as, but not yet operating as, a transporter bridge. ==Examples== File:transporter.3.750pix.jpg|The Newport Transporter Bridge can carry 6 cars and 120 passengers Image:Middlesbrough Transporter Bridge.jpg|The Middlesbrough Transporter Bridge; the gondola can carry 200 people, 9 cars or 6 cars and one minibus.
