(SR 5 Bus, Riverstone Parkway). Relocation of SR 5 I-575 is now cosigned throughout its length with SR 5, which was completely removed from its former alignment in 1985–1986 over a nearly stretch from Marietta all the way to north of Ellijay—far beyond the I-575 terminal point. SR 205 was also deleted when I-575 opened in Cherokee County in 1985, returning what is now the northernmost part of Bells Ferry Road to local responsibility. Part of its old route was briefly designated by a state project route number that appeared on maps as SR 754. This mostly consisted of a widening project planned on the route. The counties along the way did not want to fund it since the route had been state-maintained and then returned to county maintenance in 1986. When Woodstock rejected that widening project (as it would have destroyed its downtown area), SR 754 was truncated south of SR 92, and it was fully turned back in 2001 when the entire project was completed. SR 754 was not signed; however, it continued to appear on Google Maps and other Web mapping services until the mid-2010s. SR 205 has yet to be removed from Google Maps and is still shown on the northern end of Bells Ferry Road. Most of the former SR 5 did not get such treatment, and all of it was originally deleted except a portion in Canton designated as SR 5 Bus and another part that joined SR 372 to the new route using part of the old route. Another such SR 5 Bus was added from old SR 5 in Ball Ground in 1989, completing a business loop through Ball Ground that is still largely covered by SR 372. Georgia SR 5 continues northward cosigned with SR 515, Corridor A of the Appalachian Development Highway System. Along this route, SR 5 and SR 5 Alternate (SR 5 Alt) have been abandoned by the state and left to the counties and cities to maintain. The Georgia Northeastern Railroad still follows much of the old route. SR 20 exit The I-575 and SR 20 interchange was originally a half trumpet/diamond interchange. Since SR 20 has always been a heavily traveled east–west highway, traffic buildup was a common occurrence. When Sembler Properties initiated plans to construct Canton Marketplace in conjunction with a much larger mixed-use plan (Canton Place), developers sought to redesign the interchange for a
