Tennessee State Route 42

State Route 42 (SR-42) was the former designation of a state highway in Tennessee that ran from US-70S in Sparta north through Cookeville, and ending in the town of Static at US-127 near the Kentucky state line. The number was decommissioned when SR-111 was created, which runs from the KY state line to Soddy-Daisy north of Chattanooga, Tennessee. Except for a few bypasses, SR 111 follows the entire route of Old SR-42.
