Georgia will close every lane of Interstate 285 on the southwest Fulton County westside this weekend for major pavement work, starting Friday evening, August 14, 2026.
If you drive the Perimeter between Cascade Road and Martin Luther King Jr. Drive after 7 p.m. Friday, retime the trip or use the signed detours. Both northbound and southbound mainline lanes shut until 5 a.m. Monday, August 17, weather permitting.
- Where: I-285 between Cascade Road (Exit 7) and MLK Jr. Drive (Exit 9) in southwest Fulton County.
- When: 7 p.m. Friday, Aug 14, through 5 a.m. Monday, Aug 17, weather permitting.
- What closes: All northbound and southbound mainline lanes for pavement milling and slab work.
- Detours: SR 166 / Langford Parkway, I-75/I-85 Downtown Connector, and I-20.
- Next window: Another full segment shutdown is scheduled Aug 28 to 31 between Cascade Road and SR 166.
What GDOT scheduled for this weekend
According to FOX 5 Atlanta reporting on a Georgia Department of Transportation press release, crews will fully close all northbound and southbound lanes of I-285 between Cascade Road and Martin Luther King Jr. Drive. The window opens at 7 p.m. Friday, August 14, and runs through 5 a.m. Monday, August 17, weather permitting.
Weekend work covers milling and grinding concrete so slab repairs and replacements can proceed safely. GDOT says full lane closures are required so heavy machinery can operate. Drivers are urged to avoid the I-285 Westside corridor during the shutdown and to follow electronic message boards in the work zone when the road reopens.
For live statewide traffic status while the weekend window is active, open Georgia 511 before you leave the driveway or the airport curb. Message boards and 511 together beat a static map pin that still shows a green I-285 through a closed segment. If rain delays milling, 511 and GDOT alerts are the first places the restore time will move.
Detour guidance in the same report points travelers toward SR 166 / Langford Parkway, the I-75 / I-85 Downtown Connector, and I-20. Those routes will carry the diverted Perimeter traffic, so airport, stadium, and westside hotel trips that normally stay on I-285 need a new path before Friday night.
Confirmed fact is the dual-direction full closure, the Cascade-to-MLK segment, the Friday 7 p.m. to Monday 5 a.m. band, and the named detour corridors. Interpretation is that Hartsfield-Jackson airport transfers that use the west Perimeter, plus Cobb-to-south Fulton weekend trips, break first. Still unknown is whether weather shortens any night once crews are on site.
How this fits the larger I-285 Westside Rebuild
FOX 5 states the work is part of the about $206 million I-285 Westside Rebuild project, a 10-mile effort from South Fulton Parkway in College Park to Collier Road. The multi-project program rehabilitates aging concrete pavement across Fulton and Cobb counties, with final completion targeted for 2028.
GDOT has already used full weekend segment shutdowns on this corridor when slab work cannot stay inside nightly lane drops. The same report lists the next full segment shutdown for August 28 through 31 between Cascade Road and SR 166 / Langford Parkway. Treat that later window as a separate planning card once GDOT confirms the exact hours, not as proof that this weekend is longer than Monday morning.
Earlier postponements on the project have already taught drivers that weather can push a published full-closure weekend. The current card is weather permitting. Recheck GDOT and local traffic boards Friday afternoon before you commit to a detour hotel pickup or a game-day arrival path.
Deep Arrival’s Delta Air Lines guide still helps Atlanta hub travelers who connect through Hartsfield-Jackson. It does not invent an open westside Perimeter during a published full closure. Pair airline product context with live GDOT messaging for this weekend road plan.
Who needs a new weekend plan
Airport transfers between Hartsfield-Jackson and hotels or offices on the west and northwest sides are the first group. If your normal map keeps you on I-285 between Exits 7 and 9 after 7 p.m. Friday, rebuild the path on SR 166, I-20, or the Downtown Connector before you leave the curb. A rideshare that still quotes an I-285 Westside path after 7 p.m. is not proof the road is open; the app often lags a full dual-direction shutdown.
Truck and delivery fleets that stage on the westside also need a Friday afternoon briefing. A single closed segment between Exits 7 and 9 can force longer loops on I-20 or the Downtown Connector, and those loops stack when everyone discovers the closure at the same time. Publish the detour to drivers before the first 7 p.m. departure, not after the first delay call.
Event and game traffic that cuts across the west Perimeter is the second group. A Friday night or Saturday stadium trip can stack downtown congestion on top of the detour load. Leave earlier and treat I-285 Westside as closed, not as a maybe.
Through traffic that only uses I-285 as a bypass around Atlanta is the third group. The full dual-direction shutdown removes that bypass for the Cascade-to-MLK segment. Do not assume northbound remains open because you only need one direction; both directions close.
Local residents who use Cascade Road or MLK Jr. Drive ramps to enter I-285 also lose those merges for the weekend window. Plan surface routes that never depend on an entrance that is inside the closed segment.
| If you… | Do this |
|---|---|
| Drive I-285 Westside after 7 p.m. Friday | Reroute before you enter the Cascade-to-MLK segment; both directions are closed. |
| Transfer from the airport to the west side | Use SR 166, I-20, or the Downtown Connector instead of the closed Perimeter segment. |
| Attend a weekend event across town | Budget extra time for detour congestion and leave earlier than a normal Friday night. |
| Only need northbound or southbound | Still avoid the segment; GDOT is closing all lanes both ways. |
| Plan travel near Aug 28 | Watch for the next full shutdown between Cascade Road and SR 166 and recheck hours. |
- Friday start: Be off the closed segment before 7 p.m. August 14.
- Monday reopen: Expect 5 a.m. August 17 as the earliest restore, weather permitting.
- Detour stack: SR 166, I-20, and the Downtown Connector will carry extra load.
- Work zone caution: Slow down and obey message boards when the road returns.
- Next window: Hold Aug 28 to 31 as a second full-closure risk on a nearby segment.
The useful move is early and mechanical. Name the exits, pick a detour before Friday evening, and recheck GDOT and Georgia 511 if weather moves. Screenshot the detour path for passengers who will not re-read a traffic app at 10 p.m. A full dual-direction Perimeter shutdown is not a single-lane inconvenience you can thread at the last minute, and it is not limited to heavy trucks. Any car that needs that westside arc between Cascade and MLK has the same problem.
