ˈdrawbridge
Forms: see bridge.
[f. draw-: see also the earlier draught-bridge.]
1. A bridge hinged at one end and free at the other, which may be drawn up and let down so as to prevent or permit passage over it, or allow passage through the channel which it crosses.
The original form was the lifting drawbridge, used from early times to span the foss of a castle or fortification, or the inner part of it; also in more recent times to provide a passage over canals, dock-entrances, and other waterways; for this the form called a swing- or swivel-bridge, which revolves horizontally is often substituted: see also bascule. A drawbridge to permit the passage of vessels, sometimes forms a small section of a long permanent bridge.
