There are three types of bascule bridge [1] and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the span(s). The Chicago bascule name derives from the location where it is widely used, and is a refinement by Joseph Strauss of ...
Bridge 4 is a twin-leaf, Chicago-type bascule bridge, with its counterweights located under the road deck. All the other bascule bridges on the Welland Canal are single-leaf Rall-type bridges, with counterweights suspended on a frame structure over the roadway.
A bascule is a counterbalanced structure (i.e. a lever) having one end that rises as the other lowers. It may also refer to: Bascule bridge, a moveable bridge with a counterweight that continuously balances the span in providing clearance for boat traffic; Bascule (horse), the arc a horse's body takes as it goes over a jump

A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. [1]
The Andrew P. McArdle Memorial Bridge is a steel truss bascule bridge over the Chelsea Creek, just upstream of its confluence with the Mystic River and the Tobin Bridge.

Scherzer was the inventor of a refinement of the bascule bridge called the Scherzer rolling lift bridge. [1] [3] His last engineering work before he died, done in 1893, was the design of two of these rolling lift bridges in Chicago. His design pivots the bridge like a rocking horse. The friction is lowered because it is rolling friction.
