The project is located along the former Georgia Southern and Florida Railway right-of-way and the trail is being constructed on top of the existing abandoned railroad bed through (from east to west) Putnam, Clay, Bradford, and Union counties.

Construction of a 12-foot-wide (3.7 m) multi-use recreational trail along this corridor is being completed in phases, and the first paved section of 5.2 miles (8.4 km) opened in Clay County in 2008.

The paved trail now runs from western Keystone Heights through and past Florahome through the southern edges of the Etoniah Creek State Forest.

[1] The Clay County segment of the PLB Trail running through Keystone Heights ties into a 10-foot-wide (3.0 m), 5.5-mile-long bike path (8.9 km) the FDOT constructed.

This bike path runs north from downtown Keystone Heights to Mike Roess Gold Head Branch State Park.
