to Chattanooga, where the routes follow Broad Street north into downtown. At the corner of Main Street and Broad Street, US 72 comes to an end; US 76 begins at the intersection, making one highway in essence a continuation of the other. History West Tennessee Originally, US 72 followed US 45 to Selmer and followed a route west to Memphis. In 1931, US 64 replaced US 72 between Memphis and Selmer. In 1935, US 72 was routed to Memphis through Mississippi from Corinth removing the extension on US 45 to Selmer. As late as the early 1970s, US 72 followed State Route 57 (Poplar Avenue) from Collierville to its western terminus at East Parkway N. (which carried US 64, US 70, and US 79, as well as State Route 1). During the mid-1980s until the early 2000s, U.S. 72's westbound route in midtown Memphis was changed to switch from Poplar Avenue to a westbound off-ramp connection with Union Avenue (just as its name changed from Walnut Grove Road), instead of following Poplar west to East Parkway North. (In the same trend, eastbound US 72 ignored East Parkway South and continued eastward on Union—joining SR 57—until an exit ramp deposited the two highways onto eastbound Poplar.) Some signs still remain from this route change. Mississippi In Tishomingo County, US 72 originally followed the current Road 172 / Quitman Street through Iuka before being bypassed in the mid-1980s. Also, An Old US 72 exists south of US 72 between Burnsville and Glen. US 72 also followed Alcorn County Road 218 and entered Corinth on Proper Street. Until 1935, US 72 followed US 45, now Polk Street / Mississippi Highway 145 north into Tennessee. Also, included in the original 1935 routing west of Corinth followed Mississippi State Route 2 / Kossuth Road to Kossuth before turning west. Continuing westward, yet another segment of Old US 72 exists south of US 72 in Benton County from just west of the Tippah County line to just east of the Wolf River near Canaan. The bridge across the Wolf River collapsed due to flooding and is now closed; much of this segment is now on private property and little evidence of pavement remains due to washout and ecological succession. The continuation of this segment west of Wolf River to Mississippi Highway 5 is signed Wyatt Road. Finally, there is one more route that may have been
