What are drawbridges used for?
A drawbridge (bascule bridge) is utilized where the low clearance of a bridge over a waterway would not allow some ships and boats to pass beneath it. This is most commonly seen on active waterways where a bridge is desirable for traffic, but taller/larger ships and boats MUST pass through. Alternatives to drawbridges include vertical lift bridges, where the middle section can be raised high enough to allow ships beneath it, and swing bridges that can pivot in the center. Counter-weighted drawbridges, however, are more common, because they were usually cheaper and easier to construct. In many cities with high vehicular traffic, or for interstate highways, drawbridges have been replaced by modern high-rise bridges.
