About the Project

This project reconstructed the culvert at Portsmouth Road (Route 1529) over Flat Branch, near Deward Court and Fairmont Avenue in Prince William County.  The previous culvert, built in 1980, was structurally deficient and consisted of three corrugated metal pipes supported by temporary shoring. The new culvert is a triple concrete box culvert. Construction began in early July 2014.
