Traffic delays reported at Johns Creek Parkway and McGinnis Ferry Road

A traffic incident at Johns Creek Parkway and McGinnis Ferry Road slowed one of south Forsyth’s most fragile commute routes, with the Forsyth County Sheriff’s Office warning drivers to expect delays or find another way around. In a corridor where even a minor disruption can ripple through school runs, afternoon pickups and emergency access, the slowdown quickly became more than a routine traffic hiccup.

The intersection sits inside a busy stretch of McGinnis Ferry Road that is already under active widening work. Forsyth County says drivers can expect periodic single-lane closures and flagging between 9 a.m. and 4 p.m. Monday through Saturday as crews continue work along the road between Sargent Road and Caney Creek. The broader project covers about 2.5 miles from Douglas Road to Hospital Parkway, placing the area under constant pressure even before any new incident appears.

County and city officials broke ground on the widening project on March 11, 2025, signaling a long-term rebuild of a road that connects fast-growing south Forsyth neighborhoods with Johns Creek traffic patterns. County materials say the work includes clearing and utility relocation in the corridor, and the project has already been tied to state support. In August 2024, Forsyth County said it received $120 million in state funds, including $10 million set aside to help fund the McGinnis Ferry Road widening.

The traffic headache at Johns Creek Parkway also lands as state work on SR 400 adds another layer of disruption north and south of the corridor. Georgia Department of Transportation said heavy construction for the SR 400 Express Lanes project in Forsyth County was expected to begin in April 2026, starting between McGinnis Ferry Road, the future Exit 11B, and McFarland Parkway. GDOT also said a new SR 400 Incident Response Unit would operate 24/7 along the 16-mile project corridor to help motorists and manage incidents.

For drivers trying to move between Johns Creek, south Forsyth and the SR 400 corridor, the message is simple: plan for extra time and expect backups to spread beyond the immediate intersection. With widening work, utility relocation and express lanes construction all converging in the same part of the county, the traffic pattern around McGinnis Ferry Road is likely to stay volatile well beyond this latest delay.
