The Cotter Bridge is the only bridge in Arkansas known to be designed and engineered by the Marsh Engineering Company, a significant twentieth-century bridge-building company. Among the largest they ever designed, it is also an excellent example of the company's patented Marsh Rainbow Arch. A unique feature of the bridge is that it was constructed by means of a cableway, suspended across the river, over which all materials were transported to various parts of the structure. The Cotter Bridge was instrumental in making accessible a new region of the Ozarks, an important recreational area in the United States. It became Arkansas' first National Civil Engineering Landmark in 1986.
