It heads north, concurrent with SR 211, as a two-lane road through a business district before traveling through wooded areas and crossing a bridge over the North Fork of the Forked Deer River into downtown. US 51 Bus./SR 211 pass by the Dyer County Courthouse and becomes concurrent with SR 104 (East Court Street) as the road becomes North Main Avenue shortly before making an abrupt left turn onto McGaughey Street.
