I-285 is fully closed in southwest Atlanta all weekend — GDOT asks truckers to take the detour this time

Interstate 285 is fully closed in both directions in southwest Atlanta this weekend, and the Georgia Department of Transportation is asking truck drivers to follow the posted detour after blaming tractor-trailers for much of last weekend's gridlock, according to CDLLife on Oct. 23.

The closure runs from 7 p.m. on Friday, Oct. 23, until 5 a.m. on Monday, Oct. 26, on the westside of Atlanta between Cascade Road at exit 7 and Highway 166 — SR 166/Langford Parkway — at exit 5. GDOT's own advisory, issued Oct. 19, confirms all northbound and southbound lanes are closed between those exits, weather permitting, while crews mill and grind the roadway concrete in preparation to repair or replace concrete slabs through the project area.

The work is part of the I-285 Westside Rebuild, a $206 million concrete slab reconstruction and rehabilitation project running along the westside corridor from SR 14/South Fulton Parkway in College Park to Collier Road. It is one of two projects on the westside corridor designed to repair or replace concrete slabs, and it is scheduled for completion in 2029. GDOT says the lane closures are necessary to give crews room to work safely while large equipment is in operation, and it urges drivers to rely on the 511GA app as the primary source for real-time traffic conditions and closure details.

Why the warning to truckers is pointed this time: last weekend, a separate I-285 closure in Smyrna produced two days of gridlock in and around the construction zone, with some motorists reporting, per 11Alive, a 30-minute drive time to travel a half mile. GDOT says tractor-trailers were to blame for a lot of the backups, pointing to truckers who ignored posted detours. Local trucking leaders answer that many drivers were simply confused, and that there is not enough posted signage to properly direct truck drivers to the Interstate 75 southbound detour, which takes them downtown and onto the Connector at I-75/85.

Both sides are now working on the fix in public. GDOT says it is working with the Georgia Trucking Association to spread the word about the detours to carriers in and outside the state, to get more signage posted, and to facilitate better coordination with law enforcement. For this weekend, GDOT says all drivers should avoid the closure area as much as possible. The suggested detours are to use Interstate 20 or Highway 166 to get into downtown Atlanta, and then the Interstate 75/85 Connector to head north or south through the city.

For a driver running Atlanta this weekend, the practical version is short. Do not let a navigation app route you onto the westside Perimeter between exits 5 and 7 — it is closed in both directions until Monday at 5 a.m., and the surface-street spillover is where last weekend's trucks got stuck. Build the I-20 or SR 166-to-downtown routing into the trip plan before you roll, expect extreme delays on the alternates, and check 511GA rather than assuming the closure ends early. If your delivery window cannot absorb the detour, call it in early: a full weekend closure on the Perimeter is exactly the kind of delay a dispatcher would rather hear about on Saturday than at the gate on Monday.

GDOT's advisory also carries its standard work-zone warning for the corridor around the closure: pay attention to shifting travel patterns, follow roadside message boards and signage, reduce speed, move over a lane where possible for crews, wear a seat belt and avoid distractions. Message boards and signage are supposed to alert drivers in advance of the closure and its shifts — which, after last weekend, is precisely the point of dispute between the department and trucking leaders.
