As part of a larger initiative to fully integrate SmartWay across Middle Tennessee, Tennessee Department of Transportation (TDOT) partnered with Gresham Smith to design a 38-mile infrastructure expansion from Hogan Road to US 70 on the west side of Nashville, and from Earhart Road to US 70 in Lebanon east of Nashville. Closed-circuit television (CCTV) cameras will provide video monitoring while radar detection will support active traffic management from the TDOT Region 3 Regional Traffic Management Center (RTMC). Full-color dynamic message signs (DMS) will provide real-time incident information and traffic conditions to motorists. Communications to the devices will be via fiber-optic cable.
In a multi-office effort, Gresham Smith’s Transportation Systems Management and Operations (TSM&O) group first completed the design for the eastern segment of the project. Osprey Communications is coordinating the use of Right-of-Way with TDOT, and as part of this effort will install a conduit and fiber-optic cable that will be owned and used by the department. Our TSM&O’s partnership with TDOT will result in an expedited construction timeline and significant cost savings for the department.
