U.S. Route 51 (US 51), mostly overlapped by the unsigned State Route 3 (SR 3), is a north–south state highway in the U.S. state of Tennessee, that is 135.9 miles (218.71 km) long, completely within West Tennessee.[2] It begins in Shelby County and ends in Obion County. The SR 3 designation is seen largely on mileposts.

The two places where US 51 and SR 3 differ are in Memphis, where US 51 has been moved to Danny Thomas Boulevard (State Route 1 / State Route 4), while SR 3 remains on the one-way pair of 2nd and 3rd Streets, and in South Fulton, where US 51 crosses the state line on State Route 215 to the Purchase Parkway, while SR 3 remains on the old road, now U.S. Route 45.[1]
