The cities of Atlanta and Sandy Springs agreed this week to build a multi-use path running along one of the area’s most important roads.

The 2.3-mile trail would span Ga. 400 from Loridans Drive in the Atlanta to south of Johnson Ferry Road in Sandy Springs.

According to a presentation given to Sandy Springs City Council on Tuesday, the city plans to budget $5.5 million for its part of the trail, which would be 1.8 miles.

This would fill a gap between the existing PATH 400 multi-use path and fit in with the ongoing $800 million I-285/Ga. 400 interchange project.

The Georgia Department of Transportation is expected to build a segment of connecting trail from the north terminus through the I-285 Interchange along Peachtree Dunwoody Road, according to a Sandy Springs news release.

The cities agreed to provide 20% of local funding for the project, with an 80% federal match provided through GDOT.

The release said the Atlanta portion of the tab will be paid for by Livable Buckhead and the PATH Foundation.

According to the City Council presentation, Sandy Springs will use some Transportation Special Purpose Local Option Sales Tax, or TSPLOST, funds to cover its part of the bill.

The estimated completion date is Jan. 23, 2023.
