This new reference work addresses both the maintenance and the upkeep of existing movable bridges, as well as the complete design of new movable bridges. Comprehensive coverage is provided on engineering design and actual construction technology used in building all major types of bridges, including all structural issues and relevant mechanical and electrical systems used to make such bridges functional. Includes coverage of vertical lift, swing, and bascule bridges for both highway and railway usage Offers valuable guidance on operation, maintenance, inspection, and rehabilitation of moveable bridges

The location of the Cerritos Channel between two major international ports dictated the use of a movable bridge design for the Heim Bridge that would allow for large ship traffic between the two ports. The U.S. Navy was the major proponent of the bridge during World War II because of its need for more efficient transportation between the naval base on Terminal Island and the mainland. The bridge is a rare example of a movable bridge of any type in southern California; it is one of the large vertical span bridges in the western United States. It was determined as eligible for listing on the National Register of Historic Places in 1998.
