Movable Bridge

A movable bridge is a type of bridge which can be moved to allow passing of water traffic that is too tall to go under, such as boats or barges.
Types of these bridges are but may not be limited to:
* Drawbridge - the bridge deck is hinged on one end.
* Bascule bridge - a drawbridge hinged on pins with a counterweight to simplify raising.
* Rolling bascule bridge - an unhinged drawbridge lifted by the rolling of a gear along a horizontal rack.
* Folding bridge - a drawbridge with multiple sections that collapse together horizontally, allowing the bridge to fold.
* Curling bridge - a bridge with transverse diversions between multiple sections that curl vertically.
* Fan bridge - a bridge with longitudinal divisions between multiple bascule sections that rise to various angles of elevation, making a fan arrangement.
* Vertical-lift bridge - the bridge is lifted by counterweighted cables mounted on towers.
* Table bridge - a lift bridge with the lifting mechanism mounted under it.
* Retractable bridge - the bridge deck is retracted to one side.
* Submersible bridge - the bridge is submerged under the water to allow traffic to pass.
* Tilt bridge - the bridge deck, which is curved and pivoted at each end, is lifted at an angle.
* Swing bridge - the bridge deck rotates around a fixed point, usually at the centre.
* Transporter bridge - a jet bridge to an aeroplane. 
* Guthrie rolling bridge - similar to a retractable bridge.
* Vlotbrug - another type of bridge similar to that of a retractable bridge.
* Lock - allowing ship traffic to flow when open and at least foot traffic on top when closed.
