The Cherry Street Strauss Trunnion Bascule Bridge is a bascule bridge and Warren truss in Toronto, Ontario, Canada. [1] Located in the industrial Port Lands area, it carries Cherry Street over the Toronto Harbour Ship Channel and opens to allow ships to access the channel and the turning basin beyond. There are two bascule bridges on Cherry Street. The other, smaller bridge, crosses the Keating Channel, while this bridge crosses the Ship Channel.

The bridge was built in 1930 [1] by the company of Joseph Strauss and the Dominion Bridge Company. The north side of the bridge has 750-ton concrete counterweights that allow the bridge to pivot to open. The bridge uses 500 tons of steel in its construction. [2] The bridge is designed to carry two lanes of traffic. It cost CA$500,000 ($8.13 million in 2018 dollars) [3] to build. [2] It was officially opened on June 29, 1931 by Toronto Mayor William Stewart. [2] The bridge was listed under the Ontario Heritage Act by the City of Toronto in 1992 as architecturally historical.

A counterweight is a weight that, by exerting an opposite force, provides balance and stability of a mechanical system. Its purpose is to make lifting the load more efficient, which saves energy and is less taxing on the lifting machine.

Grand Street Bridge (Connecticut) bridge in United States of America

The Grand Street Bridge was a double-leaf deck-girder bascule bridge in Bridgeport, Connecticut, United States, that spanned the Pequonnock River and connected Grand Street and Artic Street. It was one of three movable bridges planned by the City of Bridgeport in 1916 at the request of the War Department during World War I. Construction was completed in 1919, but the delays surrounding the construction went to the Connecticut Supreme Court in case of Edward DeV. Tompkins, Inc. vs. City of Bridgeport, Connecticut. The court ruled in favor of Tompkins and awarded damages equal to the contract. In 1936, the bridge had excessive settling and required the replacement of its southeast pier. As part of the repairs, a new floor and electrical system were installed. In 1965, the floor was replaced with a steel grate on I-beam floor. In 1984, the eastern approach span was replaced and the northwest trunnion post was reconstructed. The bridge was closed in the 1990s and dismantled in 1999.

Steel bridges, especially ones with intricate latticework like ours, contain thousands of difficult-to-reach joints, often hiding corrosion that's accelerated by salty air. Repairing and repainting such bridges is an ongoing headache, especially compared to ones made of concrete. Nevertheless, some places re-invest in their old steel bridges. Toronto refurbished its Cherry Street Bridge for $2.6 million in 2007, and recently Boston and San Francisco spent tens of millions renovating their Strauss drawbridges as well.
