lift bridge
Elevating river crossing
A lift bridge is a movable bridge whose central span rises vertically between towers to allow tall vessels to pass beneath.
Unlike drawbridges that pivot upward or swing bridges that rotate horizontally, lift bridges maintain their flat orientation while being hoisted by cables and counterweights: The lift bridge rose to let the freighter through.
