(April 2000) Tennessee dropped the state name from its interstate signs a long time ago. Current signs have the numbers as large as they can be.
(1998) One of the few interstate signs with the state name. This sign was replaced in 1999. (Photo from Joe Koehler).
Tennessee US highway sigs in the 60's and 70's had this unusual TENN-US logo. This was used on both cut-out and later on rectangular signs.
(April 2000) Current style Tennessee state primary route marker. In 1982, Tennessee divided its routes into primary and secondary class. A route can change from primary to secondary and back to primary (TN-13 for example) and retain the same route number. With the new class of highways came this new sign. Signs are only 24" x 36".
(April 2000) Current style two-digit secondary route marker. This style was used for all Tennessee state routes prior to 1982. Earlier signs had "TENN" horizontally below the number (see below).
(April 2000) Current style three-digit secondary route marker.

Old porcelain state route marker. These were used in the 20's and 30's. Later signs were simply cutout triangles with the number and the "TENN" logo. The "L" below the route marker indicates that TN-6 veered left at the intersection ahead (My collection).
Another old porcelain state route marker. Note the slightly different font for the "6". This sign directed drivers to turn right at the next intersection. Aren't arrows much easier? (Photo from Joe Koehler)
