About the Project

This project will reconstruct the culvert at Portsmouth Road (Route 1529) over Flat Branch, near Deward Court and Fairmont Avenue in Prince William County.  The existing culvert is structurally deficient and consists of three corrugated metal pipes supported by temporary shoring. The structure was built in 1980. The new culvert will be a triple concrete box culvert. Construction is scheduled to begin spring 2015 and be completed by late summer 2015.
