The Yale Lock Bridge, also known as the Yale Bridge, is a historic bridge located in Yale, Oklahoma, United States. The bridge was built in 1924 and spans the Cimarron River, providing a vital transportation link between the towns of Yale and Stillwater. The bridge is significant not only for its age and historical importance but also for its unique design, which features a camelback truss structure. This type of structure is characterized by its curved upper chord, which gives the bridge its distinctive humped appearance.

Design and Construction

The Yale Lock Bridge was designed by the Kansas City Bridge Company and constructed by the Frisco Railway Company. The bridge’s camelback truss design was chosen for its ability to withstand the heavy loads and stresses associated with railroad traffic. The bridge features a total of five spans, each measuring 100 feet in length, and is supported by four piers and two abutments. The bridge’s deck is composed of wooden timbers, and the trusses are made of steel.

Technical Specifications

The Yale Lock Bridge has a number of technical specifications that are noteworthy. The bridge’s overall length is 540 feet, and its width is 18 feet. The bridge’s vertical clearance is 20 feet, and its horizontal clearance is 120 feet. The bridge is designed to carry a maximum load of 50 tons, and its trusses are rated for a live load of 30 tons per square foot.
