Mississippi Highway 145 (MS 145) is the designation for the parts of the old U.S. Route 45 (US 45) roadbed that the state continues to maintain or has designated. Those ten sections travel through Waynesboro, near Boice, through Shubuta, from De Soto to Meridian, through Shuqualak, through Macon, through Aberdeen, through Nettleton, from Shannon to Booneville, and through Corinth. Waynesboro US 45 was fully rerouted out of Waynesboro in 2004, and the old alignment became MS 145. MS 145 begins south of town at an intersection with US 45. It heads north through rural and wooded areas before entering the city limits as Mississippi Drive and passing through neighborhoods.
