State Route 166 Improvements

Lewis and Maury Counties

The project for State Route (SR) 166, between SR 6 (US 43) in Maury County and SR 99 (US 412) in Lewis County, includes reconstruction and widening for approximately 6.5 miles. Design plans also include construction of a new interchange at SR 6.

SR 166 is considered a rural major collector route. It connects to SR 99, providing a route between Mt. Pleasant in Maury County and the Natchez Trace Parkway and Hohenwald in Lewis County. An Advanced Planning Report (APR) was approved in 1998 to relocate and widen SR 166, as well as widen SR 99.  Currently, widening projects in Lewis Couty are nearing completion. When all planned improvements are finished, the new facility will provide improved safety, capacity, and mobility along the corridor for existing and future traffic.

Estimated construction start: The interchange at SR 6 (US 43) in Mt. Pleasant began construction in June 2016. Construction for SR 6 (US 43) in MT. Pleasant to SR 99 at the Lewis County Line is pending funding to determine the start date. 

Estimated completion*: The interchange at SR 6 (US 43) in Mt. Pleasant began completed in April 2019.  The second segment's completion is TBD

Key Project Milestones

Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way (ROW), and Construction. Proposed improvements to State Route 166 consist of two roadway projects. Due to the complexity of the project, improvements to SR 166 have been divided into two smaller sections or phases.
