 Once these two routes become concurrent, traffic averages increase to just over 2,500 vehicles per day, and then slightly taper off to around 2,200 vehicles as the route run to its northern terminus at SR 52.The first portion of the roadway that is signed as SR 183 today makes its appearance on Georgia state road maps in 1937, when SR 136 was first graded and ran from northeast of Dawsonville to intersect SR  52; it was therefore the section of today's state route from the start of its concurrency with SR 136 to its northern terminus at SR 52 (signed as SR 43 at the time) that were first extant.By early in 1941, the stretch from SR 53 to SR 136 had been graded, but neither this new stretch of roadway, nor the portion of SR 136 in the area, had been improved as far as surface conditions were concerned.
