ALPHARETTA, Ga. — Drivers in Alpharetta are dealing with closures and detours as crews work to improve drainage at the intersection of Mayfield Road and Bethany Road.

Construction began on June 23, focusing on upgrading the roundabout.

Workers will remove the central truck apron and landscaped island and install an underground rainwater detention system.

From July 14 - 20, a full closure of portions of Mayfield Road and Bethany Road will happen to complete work that cannot safely be done with traffic nearby.
