The CON/SPAN® stream crossing leads into a precast inlet structure in the residential community of Dulles Greens. The project planners addressed issues from stormwater management to wetlands mitigation. The entire structure, including the 106 linear feet of retaining walls, was installed in three days.

This project marked the 11th CON/SPAN® installation for the contractor. Contech worked closely with the engineer to design the precast weirwall.

“CON/SPAN® precast bridge is the best and quickest bridge system I’ve ever seen in more than 20 years in this business,” said Jack Wilson of Westlind Construction Co. “Every bridge section is of high quality and fits the foundations and site conditions like a glove.”
