Major intersections Special routes Cedartown loop route State Route 6 Loop (SR 6 Loop) was a short loop route of SR 6 that existed entirely within the city limits of Cedartown. Between June 1963 and the beginning of 1966, it was established from US 278/SR 6 north to SR 100. In 1976, SR 100 was shifted westward, and SR 6 Loop's northern terminus was extended east-southeast to US 27/SR 1 in the northern part of the city. In 1982, the path of SR 6 was shifted westward one block, replacing the path of SR 6 Loop. Rockmart business loop State Route 6 Business (SR 6 Bus.) is a business route of SR 6. Nearly the entire road is within the city limits of Rockmart. Its entire length is concurrent with U.S. Route 278 Business (US 278 Bus.). Dallas spur route State Route 6 Spur (SR 6 Spur) was a spur route of SR 6 that existed southeast of the city limits of Dallas. In 1966, it was established from SR 61 to US 278/SR 6. In 1983, it was decommissioned. Dallas bypass route State Route 6 Bypass (SR 6 Byp.) was a proposed bypass route of SR 6 that was proposed just outside of the city limits of Dallas. In 1983, its planned path was from US 278/SR 6 west-southwest of the city to US 278/SR 6/SR 120 southeast of it. In 1987, SR 768 was proposed on the path that SR 6 Byp. was planned to travel, thereby replacing it. Dallas–Hiram business loop State Route 6 Business (SR 6 Bus.) is a business route that travels from Dallas to Hiram. It consists of Buchanan Street, West Memorial Drive, East Memorial Drive, Merchants Drive, and Atlanta Highway. Unlike SR 6 Bus. in Rockmart, it is not concurrent with a business route of U.S. Route 278 (US 278). SR 6 Bus. begins along Buchanan Street as SR 120 turns right onto the intersection with US 278/SR 6 (Jimmy Campbell Parkway). Buchanan Street ends at West Memorial Drive, and SR 6 Bus. turns right. From that point on, it follows the former path of SR 6. Curving toward the northeast, SR 6 Bus. encounters a paved trail that turns along the south side
