What SR 400 Peach Partners does

SR 400 Peach Partners is a special-purpose public-private partnership consortium formed in 2023 to design, build, finance, operate, and maintain the SR 400 Express Lanes, a 16-mile dynamically-priced toll corridor in metro Atlanta running from the MARTA North Springs Station in Fulton County to north of the SR 400/McFarland Parkway interchange in Forsyth County. The consortium was selected by the Georgia Department of Transportation (GDOT) as the Best Value Proposer for the project, valued at approximately $4.6 billion, making it the largest transportation P3 in U.S. history and the largest transportation infrastructure project in Georgia's history. The contract is structured as a 55+ year DBFOM concession and is the first long-term DBFOM partnership GDOT has entered with a private sector partner.

The consortium is a three-party vehicle formed by Acciona Concesiones, ACS Infrastructure (a subsidiary of ACS Group), and Meridiam. Design and construction are executed by a Dragados-Acciona Construction joint venture, with Parsons serving as lead designer. Operations and maintenance will be self-performed by a dedicated project company set up within the consortium for the full contract term. Core technology components include Intelligent Transportation Systems (ITS), electronic tolling infrastructure with dynamic pricing, and a proprietary radar-based traffic management and predictive modeling platform supplied by team member Indra USA. The integrated offering spans construction, finance, and long-term operations with a workforce development and DBE program supporting local economic impact.

Revenue mechanics are anchored to two streams: tolling revenue from dynamically priced express lane usage (with rates set by GDOT and the State Road and Tollway Authority), and long-term availability-style revenue under the DBFOM concession. End users are metro Atlanta commuters and travelers on the SR 400 corridor, while the sole contracting counterparty for the concession is GDOT (with SRTA as co-owner and tolling regulator). The project formally broke ground on April 22, 2026, and is currently in the construction mobilization phase, meaning material tolling revenue remains years away.
