Description 

Construction began in June 1915 and cost about $132,000. F. H. Frankland, bridge engineer for the Louisiana Highway Commission, designed the bridge and supervised its construction. A $26,000 road embankment carried the highway through the cypress swamp north of the bridge.

The bridge was opened to traffic on September 15, 1916 and formally dedicated by the Interstate Inland Water League on October 27. It was part of the Old Spanish Trail through Lake Charles and became part of US 90 beginning in 1926.

When US 90 was relocated onto the current Calcasieu River bridge in 1951, the United States Corps of Engineers required the old bridge to be removed due to its poor condition and its obstruction to water navigation, having suffered many collisions from ships and barges over the years. Local citizens were unsuccessful in preventing its removal, and the Kansas City Bridge Co. dismantled the bridge in the winter of 1952-1953.

There is a very good description and photographic reproduction of the bridge's bascule section in the January 1917 issue of the Employees' Bulletin of Robert W. Hunt & Company, Engineers. [public domain].
