SR-400 express lanes PPP project in Atlanta

project in tender

This project involves the development of State Route 400 (SR-400) in Atlanta, Georgia. SR-400 is a vital transportation corridor in metro Atlanta that connects people, jobs, and freight. The project features additional lanes along 16 miles of the SR-400, providing more reliable journey times between Atlanta’s northern suburbs and downtown. Under this project, two buffer-separated express lanes in each direction between North Springs MARTA Station and McGinnis Ferry Road and one buffer-separated express lane in each direction from McGinnis Ferry Road to McFarland Parkway will be constructed. It will provide more reliable trip times and free access for transit and vanpools and reduce delay by 19,000+ hours each day in the SR-400 corridor by 2030. Once completed, the new lanes will help to ease congestion and be free of charge to public transit, emergency and registered carpool vehicles. The project will be delivered through a Public-Private Partnership (PPP) with GDOT and will be procured through a Design, Build, Finance, Maintain (DBFM) delivery model that includes a 35-year maintenance term and availability payments from GDOT.
