PATH400: Buckhead's Emerging Trail Network
Buckhead spent decades as one of Atlanta's least walkable districts, built around a highway and a handful of arterial roads with no shoulder to spare. PATH400 is the slow, segment-by-segment answer to that: a paved multi-use trail following the GA 400 corridor that now links several of Buckhead's parks and neighborhoods without a car.
Published July 6, 2026The idea behind PATH400 predates the BeltLine's popularity boom, though the two projects get compared constantly. Livable Buckhead, a community improvement district, pushed the concept in the mid-2000s as a way to give Buckhead's residential pockets — many of them cut off from each other by GA 400, Peachtree Road traffic, and a street grid that dead-ends into office parks — an actual connective path. The trail runs roughly parallel to the highway corridor, using the wide utility easement and right-of-way that the road already claimed, which is part of why it was buildable at all: land acquisition wasn't the obstacle that it is for greenways cut through established neighborhoods.
Construction happened in phases, funded through a mix of the Buckhead CID's own assessments, City of Atlanta bond money, and state and federal transportation grants earmarked for multi-use paths. That funding patchwork is normal for Atlanta trail projects — it's the same model that built out sections of the BeltLine and the Silver Comet — but it does mean the trail has grown unevenly, with well-used finished stretches next to gaps that require riders and walkers to detour onto sidewalks or side streets.
What's built and rideable now
The trail's strongest corridor runs through the area near Chastain Park, connecting into the park's own path network, and continues south toward the Lindbergh area, where it links up with MARTA rail access. Along the way it passes underneath GA 400 at several points via underpasses built specifically for the trail, which matters more than it sounds — at-grade crossings of a six-lane interstate-style highway would have made the whole project a nonstarter for anyone without a car.
The surface is consistently paved and wide enough for two-way bike and pedestrian traffic, with mile markers and wayfinding signage at major road crossings. Unlike the Silver Comet or Big Creek Greenway, which run through wooded, low-density corridors, PATH400 spends much of its length adjacent to office towers, apartment complexes, and retail — it reads more like an urban linear park than a nature trail, and the tree canopy along it is younger and thinner as a result, planted rather than inherited.
Where the gaps are
The trail's biggest weakness has historically been its southern end, where it needs to thread through some of Buckhead's densest commercial development to eventually connect toward the BeltLine's Northeast Trail. Right-of-way in that stretch is tighter, land is more expensive, and property owners along the corridor have been slower to grant easements than the utility-adjacent northern sections were. Riders attempting to go end-to-end should expect to check current trail maps before committing to a route, since a finished segment can end abruptly at a road that requires a sidewalk detour.
There's also a gap in trail character depending on which section you're on: some stretches feel genuinely separated from traffic, with landscaped buffers and sound barriers from the highway; others run close enough to GA 400 that noise is a constant presence. That's worth knowing if the appeal for you is a quiet walk rather than a commuting shortcut.
Why it matters beyond Buckhead
PATH400 is a useful case study in how Atlanta actually builds greenway infrastructure outside the BeltLine's higher profile: quietly, through community improvement districts and business-driven funding rather than a single unified authority. It shows that greenway cycling in Atlanta isn't confined to one corridor — the model of using highway or utility easements to avoid the cost of buying land through established neighborhoods is one other districts have studied since. For a car-dependent submarket like Buckhead, even a partial network like this one changes what's possible on a Saturday morning: a ride from an apartment near GA 400 to Chastain Park without touching a car door.
