 After passing the city department of public works garage it is joined by a concurrency with Georgia State Route 135.South Valdosta Road comes to an end, but US 221/SRs 31/135 turn right at a wrong-way concurrency with U.S. Route 129, which also has concurrencies with SRs 11/37/122.Georgia State Route 135's wrong way concurrency with US 129 ends as soon as it begins, because it is positioned at a pair of T-intersections set close to one another that requires a slight shift to the right for all traffic on North Carter Street.
