Duck Creek

Originally, the U.S. Army Corps of Engineers proposed a triple cell, cast-in-place 18-foot box culvert to enclose an approximately 1200-foot long stretch of Duck Creek along a complex curved alignment. The hydraulic efficiency of the CON/SPAN^® custom shape allowed the use of a single 48-foot clear span to enclose the creek.

The reduction in excavation width by 8 feet created a significant material savings and also allowed for the elimination of over 300 feet of sheet piling (a savings of approximately $1 million) needed in the original scheme to shore adjacent railroad tracks.
