The proposed route for the extension of I-69 has been divided into multiple segments, three of which impact the state of Tennessee.

  • Segment 7 (Fulton, KY to Dyersburg, TN)
  • Segment 8 Dyersburg to Milington, TN)
  • Segment 9 (Millington, TN to Hernando, MS)

TDOT transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way and Construction. To view the status of each segment, visit the project page for each segment on the TDOT website.
