Design
This is the bridge type that Chicago engineers may be most famous for. The trunnion bascule has two bridge leaves hinged on opposing riverbanks. The bridge is drawn up by giant trunnion bearings. "Bascule" is French for "seesaw"; the bridge is named for the counterweights which balance the weight of the bridge leaves.
