Interstate 65 WideningDavidson, Robertson, and Sumner Counties
Improvements for Interstate 65 from Nashville to the Kentucky state line include widening for approximately 25.8 miles in Davidson, Robertson and Sumner counties. The planned widening will address congestion, improve safety and traffic operations, and accommodate current and future traffic demands.
Due to the size of the project, construction has been split into five segments:
- From Rivergate Parkway to near State Route 41 (US 31W)
- From near State Route 41 (US 31W) to near State Route 257 (Bethel Road)
- From State Route 257 (Bethel Road) to State Route 25 (Main Street)
- From near State Route 25 (Main Street) to near State Route 109
- From State Route 109 to the Kentucky state line
Widening from State Route 109 to the Kentucky state line was completed in 2020. Widening from SR 25 to near SR 109 is currently under construction. An additional segment, the project from Rivergate Parkway to near State Route 41, is identified for funding in TDOT's 10-Year Project Plan, with construction scheduled for Fiscal Year 2025. The remaining phases are not identified for funding at this time.
Current Status: Widening from SR 25 to near SR 109 is currently under construction.
Construction Start: Widening from SR 25 to near SR 109 began in 2021.
Estimated completion*: Widening from SR 25 to SR 109 is forecasted to complete in the Spring of 2025.
Funding Source: TDOT anticipates that a portion of this project will be funded through the Transportation Modernization Funding.
History and Background
I-65 is a major cross-country north-south corridor, extending from the Gulf of Mexico to the Great Lakes. Locally, it is a connection between Nashville and Louisville, KY, serving the smaller cities of Goodlettsville, Millersville, White House, and Portland, as well as Hendersonville and Gallatin (via State Route 386, Vietnam Veterans Parkway) in Tennessee.
Between Nashville and the Kentucky state line, the existing route is primarily two lanes in each direction. This section of the interstate currently experiences high traffic volumes, which create peak hour congestion and deficient traffic operations, resulting in delays and crashes along the corridor.
The project for I-65, north of Nashville, includes widening the roadway from four to six lanes with three 12-foot travel lanes in each direction, 12-foot paved outside shoulders, 12-foot paved inside shoulders, with approximately 300 feet of right-of-way and a concrete median barrier wall where required.
Two northbound truck climbing lanes will be constructed – one between mile markers 99 and 100 and another between mile markers 102 and 104.
An auxiliary lane will also be added in each direction between the interchanges of Rivergate Parkway (Exit 96) and SR 174 (Long Hollow Pike, Exit 97) to accommodate traffic exiting and entering the roadway.
In addition to the proposed and completed widening projects, a new interchange was constructed in Sumner and Robertson counties, which connects I-65 with a new alignment of SR 109.
Weight Stations near the KY State Line
The northbound weigh station will be converted into a truck parking area, providing additional parking spaces to accommodate the increase in trucks along I-65. Construction and funding will be part of the planned section between SR 25 and SR 109.
The southbound weigh station will be updated with new scales, a truck inspection station, and additional parking spaces. Construction and funding will be separate from the planned section improvements.
