Arched Cantilever Truss

View Exhibit map

This category has been created to help progress a research project initiated by which is to identify all examples of cantilever truss bridges (both old/historic and modern) that follow the form of cantilever truss commonly called "arch cantilever." The design eliminated overhead towers in the cantilever design, by placing the extra trusses at the piers under the deck. Thus, the bridge design features a transition from deck truss anchor arms to through truss cantilever arms. See the example bridges listed in this category to help identify additional examples. BridgeHunter editors, please add any bridges you find on BridgeHunter that follow this design to this category. Also, please do not confuse this bridge design with the Suspended Deck Through Truss, which is a different type of continuous design that mimics a through arch. Thanks!
