McKenzie, Tenn.–Contractors with the TWRA have been busy at Carroll Lake recently, boosting the safety features of the newly-installed ADA sidewalk. The new sidewalk goes from the parking lot to the main fishing pier and the workers have been adding handrails to the sidewalk. They also have added netting around the pier to prevent falls into the lake. TWRA Fisheries Biologist Tim Broadbent said they also have installed two new handicapped parking spots at the lake.
