481:(Atlanta Street). Northwest of Manget Street, the highway went diagonally through existing neighborhoods, again destroying several homes. Atlanta Street was severed, but Atlanta Road was built next to it on its west side, taking more homes. Part of Powder Springs Street was permanently torn out, leaving the rest of it north to the town square as Old Powder Springs Street. The relocated Powder Springs Street was angled off to the west to become the western section of the Loop, and was extended north just past Whitlock Avenue to Polk Street.
508:) and the L&N Railroad, with the roadway tying into the extension of the new Powder Springs Street, which previously ended at Polk Street. The completion of this final leg resulted in the completion of the loop. In addition, SR 5 was relocated out of downtown Marietta onto part of the new loop to the west; it was later rerouted through a completely different city, going down Austell Road instead of Powder Springs Road, and may be rerouted yet again off of the loop and completely away from Marietta onto
535:, the previous designation of a completely different road in Marietta. SR 5 currently shares the west end of the Loop, west from Cherokee Street (northbound only) to Church Street (southbound only), southwest to Whitlock Avenue, south to Powder Springs Road, and turning east at that intersection to Atlanta Road. This is a complete roundabout and unnecessary routing, since Atlanta Road turns into Cherokee Street via East Park Square (the street's name for one block along the

Compared to the northern route, the new routing takes mainline SR 120 around Marietta the indirect way, making it a longer distance by going out of the way to the south and back north, causing drivers to turn on a different road to stay on the same highway at a third point at Powder Springs Road (in addition to either end where it turns off to original route), and causing further driving delays with more

However, the ramps still curiously remain, with the southern (eastbound) one actually used as an entrance ramp, and the northern (westbound) one connecting to Barnes Mill Road instead. Page Street had previously ended at
Fairground Street, and the extension completed all parts of the loop except one final part.

Work began again in the early 1980s to complete most of the northern quadrant when the roadway was extended from the previously-mentioned diamond interchange to connect to and take over Page Street. The planned overpass of US 41 was never built and an at-grade intersection was put there instead.

In
October 2007, the portion of SR 120 along Roswell Street between US 41 and SR 5 and SR 120 Loop was downgraded to a local city street, along with portions of SR 5. Since SR 120 required a new routing, SR 120 mainline was moved to the southern part of SR 120
