Transportation is up for discussion today during a Dawson County Chamber of Commerce luncheon. Robert Murphy, senior project manager with the Georgia Department of Transportation, will outline plans for the Ga. 53/Ga. 400 crossing, which include converting it to a two-legged continuous-flow setup. A first for Georgia, the at-grade crossing is designed to move left-turning vehicles out of traffic’s main flow by using a series of access roads and longer left-turn lanes.
