A Chicago bascule is the fixed-trunnion design of a bridge, in which the bridge rotates around a large axle called a trunnion to raise. The name was given to it because it is primarily used there. A Strauss bascule design uses counterweights to allow the bridge to pivot to open. Its name came from the name of its engineer, Joseph Strauss, who also designed the Golden Gate Bridge in San Francisco.
