Cumberland Trail. The 70-foot bridge spans Possum Creek and will make crossing the creek possible during wetter seasons.
We spent most of the first day carrying fiberglass boards in from an access point. This was done in relay teams, with two people carrying a board for roughly one-tenth of a mile to the next team. On the second day, some folks assembled crosspieces that hold the railings, others blazed trail, and my group loaded bridge parts on a zip line down the gorge.
We got a lot of work done and actually came out ahead of schedule, which was terrific.
