PSN Parsons Corporation

Parsons Corporation (NYSE: PSN) announced today that the Georgia Department of Transportation (GDOT) and the Georgia State Road and Tollway Authority (SRTA) have selected a team that includes the company as lead engineer for the State Route 400 (SR 400) Express Lanes Major Mobility Investment Program (MMIP) Project. The project is led by a Public Private Partnership (P3) awarded to SR 400 Peach Partners consisting of Acciona Concesiones, ACS Infrastructure, and Meridiam as the lead operations, maintenance, and toll operations providers. Dragados and Acconia Construction will serve as the lead construction contractors, and Indra USA will serve as the toll systems integration contractor. Parsons will serve as the lead engineer for the construction contractors.

This $4.6B project will add new express lanes in both directions along an approximately 16-mile section of SR 400 from the North Springs MARTA Station in Fulton County to approximately 1 mile north of McFarland Parkway in Forsyth County. The team will utilize electronic tolled express lanes with a 50-year concessions period, state-of-the-art traffic and incident management systems, and a digital twin asset management system. Further growth is forecasted for the corridor, with 144,000 more residents and 114,000 more jobs projected by 2050. Dynamic toll systems will improve traffic flow, reduce congestion and polluting emissions. The project will install Cellular Vehicle-to-Everything roadside technologies that will allow for Connected and Automated Vehicle supervision and orchestration.

“Parsons is proud to be a member of SR 400 Peach Partners, the team selected to partner with GDOT and SRTA on a significant roadway transportation project that will improve mobility and reduce congestion in the northern Atlanta metro area,” said Mark Fialkowski, president of Infrastructure North America for Parsons. “As leaders in design-build, our experts are helping deliver a better world through innovation in design and project delivery.”

The project also includes a $100M state bond investment for major components of MARTA’s Bus Rapid Transit (BRT) line, which will utilize the Express Lanes. The BRT line will begin at the North Springs MARTA Station and extend northward to the Windward Parkway MARTA Park and Ride, providing a seamless connection to MARTA’s Red Line train.
