A 2.3-mile bike and pedestrian trail running parallel to GA 400 is under construction and will reach Sandy Springs inside I-285 by 2029, giving Perimeter Center workers and Roswell Road shoppers a car-free route to and from Buckhead.

The PATH400 Trail Extension will stretch from Loridans Drive in Buckhead to the GA 400/I-285 interchange, adding to the existing 5.1-mile PATH400 trail. Of the total extension, 1.8 miles will sit within Sandy Springs city limits, according to the city's project page.

The price tag is substantial. Sandy Springs City Council awarded contractor F.S. Scarbrough a $20.15 million contract in May 2024 for Segments 1 and 3, which are now under construction and expected to be finished in early 2028. In December 2025, the council approved a separate $15.76 million contract to the same firm for Segment 2, which received an $18 million investment from the Atlanta Regional Commission in 2025. In April 2026, the council approved a construction agreement with GDOT for the portion running from Windsor Parkway to just north of Baroque Circle.

The trail will connect to planned multiuse paths on Peachtree Dunwoody Road and Mount Vernon Highway, creating a network that links MARTA stations, the Perimeter Center office district, and City Springs on Roswell Road.

That connectivity matters for employers. Nearly 8 percent of Sandy Springs households lack access to a personal vehicle, and 94 percent of the city's roughly 132,000 jobs are held by commuters who live elsewhere, according to the city's draft Transportation Master Plan presented in June 2026.

The Perimeter Community Improvement District is already investing in feeder trails. The PCID contributed $2.85 million toward the Mount Vernon Highway Corridor Improvement Project, which includes a bicycle and pedestrian side path now in final paving. A separate 12-foot-wide trail along Peachtree Dunwoody Road from Hammond Drive to Mount Vernon Highway is being co-funded by the city and the PCID and will connect to PATH400 and nearby MARTA stations.

When the PCID announced its Mount Vernon investment in December 2021, Executive Director Ann Hanlon said the trail "will provide those who work in the Perimeter market with a safe pedestrian connection to City Springs on Roswell Road."

The broader push fits a shift in how Sandy Springs leaders talk about transportation spending. At the June 16 council meeting on the draft Transportation Master Plan, Councilman Andrew Chinsky said, "I'm hesitant to keep spending so much on car-oriented travel thinking it's going to solve the traffic problem when it's not going to … We have to provide people other ways to get around."

Funding for the PATH400 extension comes from a mix of federal dollars through GDOT, the Atlanta Regional Commission, and local TSPLOST revenue approved by Sandy Springs and Fulton County voters in 2016 and again in 2021. The city is also managing a $750,000 HUD grant tied to the project.

All three segments are targeted for completion by 2029, according to Georgia Trend. Construction on Segment 2 is expected to begin in summer 2026.
