State Route 397 (Mack Hatcher Parkway) Extension

Williamson County


Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way and Construction. Due to the significant cost of construction, the Northwest Extension, from south of SR 96 to east of Hillsboro Road, has been divided into two smaller sections or phases.

  • Phase I Interim Improvement will include the construction of a two-lane roadway, all side road improvements, a multi-use path, and a single bridge crossing of the Harpeth River.
  • Phase II Ultimate Improvement will complete the four-lane divided facility, including a second bridge crossing of the Harpeth River.

Phase I is currently under construction.
