As reported by tnesseelookout.com, the consortium constructing Tennessee’s toll lanes along the I-24 southeast corridor has raised the stakes, committing to pay the state nearly $148 billion across 50 years to finalize the agreement, which is six times greater than the original guarantee.
A Massive Financial Shift for the I-24 Corridor
The consortium of six companies, headed by Spain’s Ferrovial, and the Tennessee Department of Transportation revealed on Tuesday that they reached a deal concerning the total amount that will be provided pay the state over the course of 50 years to nail down the contract. This total is dramatically more than the nearly $25 billion offered in August when the state initially approved the bid.
Execution of the $9.2 billion engineering undertaking falls to the consortium, which will construct toll lanes stretching approximately 30 miles from Murfreesboro to downtown Nashville, in addition to segments along I-440 and I-40 East within Nashville. Approval of DriveTN by the state’s Transportation Modernization Board hinged largely on its pledge to hand over $24.8 billion in financial concessions to the state throughout the eight-year construction phase. Recovering these expenses is planned by the consortium through driver toll fees collected in that heavily congested highway corridor across the next half-century.

Payments under the updated financial framework are projected to bring Tennessee $7.7 billion between a financial closing date scheduled for the third quarter of 2027 and the conclusion of construction in 2035. Following this, the 50-year operational phase will bring in further payments exceeding $140 billion, as outlined in a Department of Transportation release referenced by tnesseelookout.com.
24 Choice Lanes Partners Challenges Project Award
The announcement of this revised financial structure follows a challenge filed two weeks prior by a rival road-building consortium that failed to secure the project. According to tnesseelookout.com, a legal complaint submitted to the Davidson County Chancery Court by 24 Choice Lanes Partners argues that the Department of Transportation granted an unfair advantage to its competitor by permitting alterations to a historic payout agreement after the bidding period had closed.
The court documents filed by the opposing consortium claim that DriveTN was granted the opportunity to modify its terms post-bidding because it had access to the submissions of three competing groups, two of which had offered approximately $7 billion in state concessions to secure the contract.
Shortly after the initial bid was submitted, an international banking institution downgraded Ferrovial’s stock, pointing to elevated risks tied to a promised state payout that vastly outstripped rival bids. Citing an updated evaluation, Switzerland-based UBS shifted the company’s stock rating from buy to neutral, primarily because the firm had guaranteed nearly $25 billion to the state over the eight-year construction period—an amount that is now dwarfed by the newly disclosed $148 billion total linked to the 50-year agreement announced Tuesday.
A Department of Transportation spokesperson did not answer tnesseelookout.com questions by the Wednesday deadline.
