Creation: Appeared in 1923 as an original state highway, running from TN 1 (now TN 14 3rd St) downtown Memphis southeast to Mississippi.
| Adjustments: In late 1926, US 78 was added to TN 4 throughout About 1930, TN 4 was removed from Pidgeon Roost Rd at the state line; Tuggle Rd/TN 175 at Capleville; the very discontinuos segments of Pidgeon Roost Rd on both sides of the Perkins Ave interchange (the freeway was built over the original TN 4 alignment decades later); abandoned segment of Pidgeon Roost Rd to the west that has been destroyed by the I-240 interchange and the neighborhood to the northwest. Between 1952-56, TN 4 was extended west slightly to 2nd St as TN 14 was put on one-way splits downtown. Around 1968, TN 4 was given, if not officially, at least functionally one-way splits to accomodate the new downtown I-240 interchange. Westbound uses the original routing of Dr. Martin Luther King Blvd to reach Linden. EB started using East St and Crump Blvd. About 1976, TN 4 was removed from the two Old US 78 segments at the state line area About 1976, TN 4 was also removed from what are now two disconnected segments of Old Lamar Ave as part of the Perkins Ave interchange. In 1983, TN 4 was rerouted to follow Crump Blvd from Lamar Blvd (replacing TN 1 Spur), then replacing TN 83 and TN 3 Spur Danny Thomas Blvd north to its current endpoint at Chelsea Ave. The old routing via Linden/Dr. King Blvd became TN 278. Posting: TN 4 is completely unposted, even on its independent section on Crump Blvd. It is considered primary throughout. Secret US Route Overlay: US 51 (1.8 mi) US 64-70-79 (1.2 mi) US 78 (14.0 mi) Comment: TN 4 southeast of Memphis is extremely busy. Upgrading it to a full freeway east of the outer I-240 interchange would be terrific but this would be hugely expensive given the urbanization of that part of Memphis.
