Goodlettsville: I-65 widening adds new lane-swap interchange
Drivers on I-65 and US-31W will soon cross to the opposite side of the highway during construction that targets a November 2027 finish.

Drivers passing through the Davidson and Sumner County border face a new set of challenges as construction crews break ground on a diverging diamond interchange. The project connects Interstate 65 with U.S. Route 31W in Goodlettsville and marks the latest shift in a multi-year road expansion.
The Tennessee Department of Transportation announced the start of work this week. The design forces traffic to briefly switch sides of the highway. Vehicles will cross to the opposite lane, pass under the interstate, and return to their original side. State officials argue this layout reduces conflict points and enhances safety for motorists.
Crews are currently focused on earthwork. They are grading the site and installing drainage systems. Retaining walls and curbs will follow once the ground is prepared. This construction arrives while I-65 is already narrowed by an ongoing widening effort that began in March 2025.
The current phase is the third segment of a larger plan to expand the interstate from the Kentucky border to Nashville. Traffic disruptions are expected to intensify as the project merges two major roadways.
TDOT projects the interchange, along with the full widening project, will be completed in November 2027. Until then, commuters in Goodlettsville must navigate a site where two major infrastructure projects overlap.
