Traffic build up at the intersection of North Arnold Mill Rd and Arnold Mill Rd in Woodstock, GA can seriously affect commuters. A large proportion of the traffic turns right from North Arnold Mill Rd onto Arnold Mill Rd, but if just one car is continuing straight onto Barnes Rd, there is no room for the long line of cars to go around the one going straight. If a right turn lane were constructed, it would alleviate much of the traffic congestion.
