State Route 136

Putnam County

The Tennessee Department of Transportation (TDOT) is constructing improvements on South Jefferson Avenue (State Route 136) in Putnam County. This 2.3-mile project extends from north of the State Route 111 interchange to south of the Interstate 40 interchange. Improvements include widening the 2-lane roadway to 5 lanes (2 travel lanes in each direction with a dedicated center turn lane) and the addition of a 4-foot shoulder in both directions. Drivers will also benefit from improved drainage systems, streetlights, traffic signals, sidewalks, and curb-and-gutter throughout.

Current Status: The contractor has been addressing final punch list items over the past several months. Remaining work includes replacing the temporary signal at Henley Drive with a permanent signal, completing installation of several standalone overhead light poles on the north end of the project, and finishing permanent thermoplastic striping in a few remaining locations throughout the corridor.

Estimated completion*: Winter 2026

Funding Type: 80% Federal / 20% State Funding

Traffic Impacts

All lanes of traffic are now open and operational, and all side roads have been opened. As miscellaneous work continues, temporary lane closures or periodic traffic stoppages will be necessary throughout the project limits. Motorists are encouraged to use caution while traveling through the work zone and be aware of construction personnel.

Work on a concrete median island is scheduled to be completed by the end of July, and the remaining paving is scheduled for the first week of August. In addition, permanent signs and pavement markings are also scheduled for the first week of August.
