Georgia’s SR 400 Express Lanes: Leadership, Public Value, and the Future of Managed Lanes

A strategic look at Georgia’s record-setting managed lanes procurement. The conversation centers on public value, political leadership, procurement discipline, and the long-term role of revenue-risk models. 

This session will spotlight the SR 400 Express Lanes—a 16‑mile, revenue‑risk DBFOM concession that is redefining how Georgia delivers mega‑projects. Leaders from GDOT and the SR 400 Peach Partners consortium (ACS Infrastructure, Acciona, and Meridiam) will explore how they structured a 50‑year P3 to tackle severe urban congestion while keeping general‑purpose lanes toll‑free, integrating Georgia’s first express lane transit service, and deploying dynamic tolling and full‑corridor safety and traffic management technology.

Panelists will unpack the “extraordinary” financial results enabled by federal tools such as the largest‑ever TIFIA loan and a record‑setting P3 bond issuance, alongside approximately $4 billion in concession payments to the state.

Discussion will focus on risk allocation, lifecycle performance accountability, lessons from other managed lanes projects, and which elements of the SR 400 model can be replicated in other corridors and states to accelerate delivery and improve mobility outcomes.
