The Georgia State Transportation Board has selected Top End Mobility Group to design and construct new express lanes on the I-285 corridor. The private consortium will pay the state $23.6 billion for a 50-year toll revenue concession.
Why it matters
This public-private partnership shifts infrastructure financing in Georgia, requiring operators and firms in the region to account for long-term traffic pattern changes and construction impacts through 2040.
The project is backed by a $23.6 billion concession fee paid to the state, with an initial $8.9 billion phase already planned. The consortium secures 50 years of toll collection rights across the I-285 corridor, a duration that significantly exceeds typical state construction contract terms.
The players
Top End Mobility Group
A private infrastructure consortium tasked with financing, designing, and operating regional highway toll assets.
State Transportation Board
The governing body responsible for setting state transportation policy and awarding major infrastructure contracts.
State Road and Tollway Authority
A state entity that oversees toll infrastructure and establishes the dynamic pricing mechanisms for managed lanes.
The details
Under this agreement, the private consortium finances and builds the express lanes in exchange for the rights to collect dynamic tolls. The State Road and Tollway Authority retains control over pricing caps to manage traffic flow, while the design focuses on adding two outer-loop lanes between Henderson Road and Northside Drive. Businesses operating along this route should expect long-term construction logistics, with the first phase targeting a 2034 completion.
Timeline
October 15, 2026: The State Transportation Board approved the consortium selection.
December 2026: GDOT and the consortium are expected to sign the formal agreement.
late 2027 or 2028: Construction may begin on the project.
2034: The target opening date for the first phase of express lanes.
2040: The estimated completion date for all project phases.
Market Landscape
The project follows the financing model established by the Georgia Public-Private Partnership Act, which allows private entities to assume construction risk for long-term revenue rights. This selection marks a major scaling of such partnerships in Georgia, setting a new benchmark for private capital involvement in state-wide highway expansion.
Businesses in the I-285 corridor should prepare for decade-long traffic disruptions and evaluate how dynamic tolling impacts their logistics costs and employee commute times. Management teams should track upcoming GDOT procurement updates for potential subcontracting or supply chain opportunities associated with the 2027 or 2028 construction start.
The takeaway
Large-scale infrastructure projects of this magnitude will fundamentally alter regional accessibility and operational costs for commuters and freight alike. Monitor the final contract signing in December 2026 to identify specific project milestones and lane-access policies for commercial vehicles.
What happens next
The state and the consortium are scheduled to sign the final agreement in December 2026, which will likely provide more granular details on the construction timeline and the exact toll structure.
