Heads up for Northside freeway drivers: For a seventh year, a portion of Ga. 400 southbound in Roswell will be shut down early Sunday to allow more than 1,500 bicyclists onto the road as part of the Ga. 400 Hospitality Highway Century Ride.

Roswell officials said 400 southbound from Exit 7 (Holcomb Bridge Road) will be closed southbound to Exit 6 (NorthridgeRoad) from roughly 6:55 to 7:30 a.m. Also, part of Holcomb Bridge Road will close from roughly 6:40 a.m. to 7:20 a.m. to allow cycle riders to go from Market Boulebvard to the Ga. 400 ramp.

Officials caution the times when roads are expected to re-open are an approximation.
