CHANTILLY, Va., April 27, 2026 (GLOBE NEWSWIRE) -- Parsons Corporation (NYSE:PSN) joined the Georgia Department of Transportation (GDOT), the State Road and Tollway Authority (SRTA), project partners, and community leaders to mark the groundbreaking of the State Route 400 (SR 400) Express Lanes Project on April 22. SR 400 is the largest transportation infrastructure project in Georgia's history and the largest transportation public-private partnership (P3) project in the United States.

Parsons serves as the lead designer on the SR 400 Peach Partners team, supporting delivery of the approximately $4.6 billion project. The project will add new, dynamically priced express lanes along a 16-mile corridor from the North Springs MARTA station in Fulton County to McFarland Parkway in Forsyth County, improving mobility and the regional economy, enhancing travel reliability, and supporting future transit opportunities in one of the region's most heavily traveled corridors.

"This project represents a significant investment in the future of transportation in Georgia," said Mark Fialkowski, president of Infrastructure North America, Parsons Corporation. "Parsons brings deep experience delivering complex, large-scale infrastructure programs, and we are proud to support this transformative project that will improve mobility, strengthen regional connectivity, and support long-term economic growth."

The SR 400 Express Lanes Project is a key component of Georgia's Major Mobility Investment Program and is designed to address increasing congestion while providing reliable travel options for commuters and freight. The project will also enable future multimodal improvements, including transit enhancements along the corridor.
