JTC Running presents Groundwork Jacksonville with a $50,000 donation for the development of a comprehensive trail master plan for the Emerald Necklace. Originally envisioned by famed architect Henry Klutho more than 100 years ago, the Emerald Necklace will encompass approximately 14-miles of trails, greenspace, parks and waterways that encircle the urban core and link our urban neighborhoods and downtown to Hogans Creek, McCoy’s Creek, the S-Line Rail Trail and the North bank and Southbank Riverwalk’s.
