State Route 1 (SR 1), known as the Memphis to Bristol Highway, is a 538.8-mile-long (867.1 km) mostly-unsigned state highway in the U.S. state of Tennessee. It stretches from the Arkansas state line at Memphis in the southwest corner of the state to Bristol in the northeast part. Most of the route travels concurrently with U.S. Route 70 (US 70) and US 11W. It is the longest highway of any kind in the state of Tennessee. The route is signed as both in the state of Tennessee, a Primary and Secondary Highway (at different times throughout its designation)
In 2015, the Tennessee Department of Transportation erected signs along SR 1 showing motorists they are traveling on the Memphis to Bristol Highway, Tennessee's first state road. TDOT installed the signs at every county line while it celebrated its 100th anniversary.
