Meridiam, together with Acciona and ACS Infrastructure—known as the SR 400 Peach Partners consortium announced that its SR 400 Express Lanes Project has successfully reached financial close. The financial close comes after the Georgia Department of Transportation (GDOT) named the Consortium as Best Value Proposer in August 2024 and the Project reached commercial close in November 2024. Construction is expected to be completed by Spring 2031.

The total investment for the project is approximately US$11 billion, including the almost US$3.9 billion partnership with the US Department of Transportation (USDOT) via the largest ever Transportation Infrastructure Finance and Innovation Act (TIFIA) Loan to date and a US$3.4 billion Private Activity Bonds issuance.

Under a nearly 56-year design, construction, finance, operation, and maintenance (DBFOM) contract with the SRTA, the Project will provide faster, safer, and more reliable travel options for daily commuters in Fulton and Forsyth counties by:

• Upgrading a 16-mile-long corridor in the north of Atlanta, with additional dynamically tolled free-flow express lanes in each direction;
• Upgrading several key bridges along the route;
• Constructing two stations for MARTA’s Bus Rapid Transit line, which will ride for free in the Express Lanes;
• Incorporating a state-of-the-art traffic management solution that will streamline traffic flow and alleviate congestion during peak hours.

The Project’s design and construction will be carried out by a joint venture between Flatiron-Dragados and Acciona, while the Consortium will oversee operation and maintenance under a dedicated project company.
