The southbound lane of the Krog Street Tunnel will be closed starting July 1  as crews work to extend the Beltline’s East Side Trail.

The closure will last through July 21 and will take place between 9:30 a.m. and 3:30 p.m.

The extension will bring the trail south from Irwin Street to Kirkwood Avenue.

“As part of this work, new lighting and handrails will be installed within the Krog Tunnel, creating a pedestrian-friendly environment beneath the rail yard,” the announcement says. “Additionally, Atlanta BeltLine, Inc. will address safety issues at the intersection of Krog Street and DeKalb Avenue by installing a pedestrian scramble, completely halting traffic and allowing pedestrians to traverse the intersection.”
