The main span of the bridge is 170 feet (52 m) long, which was the longest beam span or concrete truss in the US when it was built. It was part of State Route 162 until it was replaced by a new span in 2015.
Design
editThe bridge design uses a hollow-box system, which was suggested to the design company of W. H. Witt Company by Homer M. Hadley.
The bridge was then built by Dolph Jones.
The bridge was built to replace a steel span that had been washed out by the flooding river in 1933.
Because of economic conditions, the concrete design was chosen over a steel design, with a savings of $826, in addition to lower maintenance costs.
The bridge is unusual in that it combines concrete with the half-through truss design, which was usually built with steel.[3]
Construction
editThe previous bridge was damaged in 1933, but the replacement bridge was ready to open in 1934, despite the Great Depression.
Historic preservation
editThe bridge was added to the National Register of Historic Places in 1982. It was saved from demolition after its replacement by a new bridge carrying State Route 162, which opened in 2015.[4]
