Creation: Appeared in 1950 running from US 25W-70 near Underwood to TN 66 (now TN 338) near the Douglas Dam.
  Adjustments: In 1975, TN 139 east was truncated to TN 66 Henry Cross Roads.    
 In 1983, TN 139 east was re-extended along its original routing (east of TN 338 was old TN 66) to the Douglas Dam area, then further east to TN 92 Dandridge; separately, TN 139 west was extended east with US 25W-70 to Four Points, then northwest as new routing to US 11W Strawberry Fields.
 Posting: Posted as secondary routing throughout
 TN 139 is not posted on its overlays with US 25W-70.
 Secret US Route Overlay: None
 Comment: Runs along the north shore of Douglas Lake
 Tn 139 is blown off by I-40 but access isn't too hard via either TN 66 or Kodak Rd.
