Construction began in April of 2017 on the Central Railroad Corridor Greenway Pedestrian Overpass that traverses I-95. It now is officially open and connects a 2-mile pedestrian path from the North County Regional Park to the Fellsmere Trailhead Preserve following the path of the historic railroad that once ran from Sebastian to Fellsmere. The pedestrian path eventually is slated to span the original 15-mile railroad route.
Easy access, parking, beautiful bathroom, interpretive displays, and a playground can be found at the Fellsmere Trailhead located on County Road 510 just west of I-95 …
The improved wide pedestrian path wends through pine flatwoods, freshwater wetlands, and vestiges of hammock.
