A Spanish Toll Company Just Bought Fifty Years of Your Commute

The state has picked its partner, and the number attached to it is the largest in the history of Tennessee transportation.

Tennessee's Transportation Modernization Board voted unanimously this week to hand the I-24 Southeast Choice Lanes project to a consortium calling itself DriveTN. The group will build two optional toll lanes in each direction along roughly 26 miles of Interstate 24 — downtown Nashville to Murfreesboro, the exact stretch that has been the daily tax on living here for the better part of two decades.

DriveTN pays the construction bill. All $9.2 billion of it. Not a bond issue, not a gas-tax increase, not a line in the state budget — private money, up front, on the single most congested corridor in Middle Tennessee. In exchange, the consortium collects the tolls for the next 50 years and has promised the state something on the order of $24.8 billion in concession payments across that term. Nothing of this size or structure has been attempted in Tennessee before.

Who is actually building it

DriveTN is led by Ferrovial, the Spanish infrastructure group whose toll-road arm has spent thirty years building and running priced lanes in Texas, North Carolina and Virginia. Alongside it sit Transurban, the Australian company that operates a large share of the toll network around Washington, D.C., and the infrastructure investor Tikehau Star Infra. These are not local road builders. They are the small handful of firms on earth that do exactly this — finance a highway, build it, and run it as a business for half a century.

That is worth sitting with for a second. The route between Murfreesboro and Nashville has been a public road since the Nashville–Murfreesboro Turnpike was chartered in the 1830s — which was, as it happens, a private toll pike, with gates and gatekeepers and a fee for passing through. Tennessee spent the twentieth century making its roads free. The 26 miles under discussion here are about to become the first stretch in the modern era where paying is an option again.

What it means for a Rutherford County commuter

The rules matter more than the headline, so here they are plainly.

The lanes you drive now stay free. Every existing general-purpose lane on I-24 remains open and untolled. The choice lanes are new pavement built alongside them. Nobody is converting a free lane into a paid one.

The price will move. Tolls are dynamic — they rise when the corridor is jammed and fall when it is not. The state has attached a performance floor to that: the choice lanes are supposed to keep traffic moving at a minimum of 45 miles an hour, and the pricing is the lever that enforces it. If a morning ever comes when the toll lane is crawling too, the deal is not working as written.

You will not be handed a bill at a booth. Collection will be electronic — some combination of license-plate reading, a windshield tag or a transponder. The exact mechanism has not been finalized. We covered how the pricing and payment side is expected to work in more detail earlier.

Orange barrels are still a while out. Construction does not begin until the deal reaches financial close, expected in 2027, and the build is projected to run about eight years — though sections are likely to open as they finish rather than all at once at the end.

The part nobody is talking about yet

Buried in the agreement is a right of first refusal, and it is the most consequential sentence in the whole package. If Tennessee later decides to extend choice lanes north along I-24 and I-65 through downtown, east along I-40 toward the airport, or — and this is the one that matters here — south through Murfreesboro to I-840, DriveTN gets first crack at building them.

Read that as a map of where this is going. The I-840 loop is Rutherford County's southern edge. A choice-lane extension that far south would put priced pavement past most of Murfreesboro's growth, not merely at its northern doorstep. That decision has not been made, and nothing obligates the state to make it. But the option is now held by a company with $9.2 billion already committed to the corridor and every commercial reason to want more of it.

There was also a quiet win in the design. Earlier concepts for the South Nashville segment would have taken roughly twenty businesses by eminent domain. The DriveTN alignment spares a longtime Asian grocery and a townhome community that had been in the path. For the families and owners involved, that redraw is the entire story.

Why here, and why now

None of this is happening because I-24 is uniquely badly designed. It is happening because Rutherford County grew faster than the road under it. Murfreesboro was a college town of about 45,000 in 1990. It is a city of more than 175,000 now, and it feeds a commute that empties north every morning and refills every evening along a corridor that was never widened to match. The city has been trying to relieve that pressure locally for years — through the Stonesbattle Parkway corridor plan and a long list of intersection and arterial projects — but no amount of city road work fixes twenty-six miles of interstate.

So Tennessee did the arithmetic and concluded it could not pay for this on its own timeline. Whether trading fifty years of toll revenue for a highway you get in eight is a good deal depends entirely on what you think your morning is worth. Ask anyone sitting at the Sam Ridley exit at 7:40 a.m. and you will get an answer fast.
