Description 

The bridge is considered significant as it appears to be a singular entity. This is based on Criterion C, representing a type (reinforced concrete through girder), period (early twentieth century), method of construction (arch-rib floor system), and is the work of a master (the firm of Mayberry and Parker, important early reinforced concrete engineers), with its significance in the area of engineering.
