Phase 2

Lane Control Gantry installation and ITS upgrades

Phase 2 of the I-24 SMART Corridor project focuses on the installation of overhead lane control gantry message boards and Intelligent Transportation System upgrades.

The I-24 SMART Corridor project will integrate freeway and arterial roadway elements, along with physical, technological, and operational improvements, to provide drivers with accurate, real-time information and to actively manage traffic for a more reliable commute.

Stansell Electric Company Inc. will first construct the lane control sign gantries and then install the necessary communication devices. Once the gantries are up, testing will be conducted in the following months.

The work will be done in the overnight hours to limit impacts to traffic. The current plan is to work two weeks on then one week off, weather permitting. TDOT will implement the following lane closures and rolling roadblocks as the gantries are erected.

For work on the eastbound lanes:
Double right-lane closure eastbound and single left-lane closure westbound will be used to set up equipment. Rolling roadblock eastbound will be used to fly the gantry and attach to the uprights.

For work in the westbound lanes:
Double right lane closure westbound and single left lane closure eastbound will be used to set up equipment. Rolling roadblock westbound will be used to fly the gantry and attach to the uprights. The first week of work will begin April 3 and will stretch from mile marker 55 to 60.

Each week’s schedule and location will be listed in the weekly Middle Tennessee Lane Closure Report, which can be found in the TDOT newsroom. Phase 1 of the project was completed in December 2021. Phase 2 is expected to be completed in the spring of 2023.
