JOHNS CREEK, Ga. â Johns Creek is making plans for improvements along one of the most traveled arteries in the city, Medlock Bridge Road. Although traffic counts vary along the corridor, about 50,000 vehicles travel the road daily. Because the corridor is prone to traffic congestion, especially at the intersections, it was identified as a TSPLOST Tier 1 project with an improvement budget of $10 million. Five intersections have been identified for improvement, at Abbotts Bridge Road / Ga. 120; at Bell Road; at Skyway Drive; at McGinnis Ferry Road; and at Johns Creek Parkway. The improvements, which are overall estimated at around $8.6 million, are designed to add capacity to the intersections through restriping or lane additions.
