If your weekend plans involve I-285 on Atlanta’s westside, it might be time for a backup plan. Contractors for the Georgia Department of Transportation will close every northbound and southbound lane of the interstate between the Cascade Road and Martin Luther King Jr. Drive exits from 7 p.m. Friday, May 8, through 5 a.m. Monday, May 11. The full shutdown is meant to give crews room to mill, grind and replace damaged concrete slabs, and officials are already warning of heavy delays on I-20, the Downtown Connector and nearby surface streets.
The work is part of a roughly 10-mile pavement rebuild on the westside that focuses on repairing and replacing worn concrete, according to Axios. Project materials from the Georgia Department of Transportation outline a phased reconstruction of the corridor, and the agency says the job requires heavy equipment and uninterrupted workspace to speed up slab repairs.
Detours and travel advice
While the interstate is shut down, southbound I-285 traffic will be pushed onto I-20, and northbound and westbound drivers will be routed onto SR-166/Langford Parkway toward the Downtown Connector, according to FOX 5 Atlanta. Transportation officials say those detours could funnel thousands of extra cars onto already-crowded interstates and spill even more traffic onto smaller neighborhood streets.
Why crews need the full closure
GDOT plans to mill and grind existing pavement, then bring in heavy machinery to remove and replace concrete slabs. The agency says that kind of work is significantly safer and faster when crews are not threading the needle between live traffic lanes. The broader corridor reconstruction has attracted multiple contractors and suppliers as part of a multi-year program, and a recent contract announcement tied to the project points to construction activity continuing through spring 2028, underscoring that weekend closures are only one part of a long schedule, according to Smith-Midland / Nasdaq.
Neighborhood impacts and weekend events
Local two-lane arterials such as Donald Lee Hollowell Parkway are expected to carry a lot of the overflow as drivers hunt for workarounds, Axios reports, so residents should brace for clogged neighborhood streets and longer local trips.
All of this hits the same weekend the downtown Sweet Auburn Springfest is set for May 9–10, and festival organizers and attendees are being urged to plan for longer travel times and consider MARTA or other transit options, according to coverage of how the event takes over downtown Atlanta.
For anyone who cannot avoid the area, officials recommend building significant extra time into travel plans, following posted detour signs and checking real-time conditions on the state’s travel site and app. The official Georgia 511 service at 511GA offers live alerts, traffic camera views and updated detour details to help drivers navigate the weekend shutdown.
