Two contracts were let by the Calcasieu Parish Policy Jury for the construction of the bridge in March 1922: to the Pensacola Ship Building Co. (Pensacola, FL) for the steel trusses, concrete floors, counter weight, and towers ($83,900); and to the Foundation Co. (New York, NY and New Orleans, LA) for the main bridge foundation and four river piers ($68,700). Construction began in the spring of 1923. A third contract was let by the Louisiana Highway Commission in November 1923 to Banta & Mutersbaugh (Lake Charles, LA) for the creosoted timber trestle approaches ($40,000). The total cost of the project was estimated at $300,000.

The bridge was opened to traffic on April 16, 1924, replacing the Moss Bluff Ferry. It was dedicated to the World War I veterans of Calcasieu Parish. The bridge was part of State Route 42, which became US 171 in 1926.

Both the Moss Bluff and English Bayou bridges were bypassed by new four-lane spans on the relocation of US 171 in 1969. The bridges were demolished around 1972.
