Swinging bridges have long been used in the Appalachian Mountains for folks to get from one mountain to another in the shortest amount of time. These bridges are made of steel cable, wood, rock, and a lot of sweat. The fun thing about a swinging bridge is that they really do swing, and while completely safe to cross, they are a bit scary.
At Foxfire Mountain you can cross the longest swinging bridge in 
America. This bridge goes from the base camp at Foxfire Mountain across Dunn’s Gorge to Prosperity Mountain. The bridge, known as America’s Bridge to Prosperity, is 4 feet wide and over 400 feet long (one and a third times the distance from goal post to goal post across a football field).
The Bridge Adventure at Foxfire Mountain includes the Bridge to Prosperity followed by a covered walking bridge, where you can hang a wish to blow in the winds of prosperity. Hidden in the trees is a new tree canopy walk, a series of rope bridges strung through the trees. Hike your way up to the Lost Mine Falls and cool off in the mists below. Watch as other guests zip overhead. The trail also leads to the smaller Cliffhanger Swinging Bridge which is only 30 ft. long but goes over the top of the falls, so you can peer 60 feet below into the pooling water. The entire bridge experience takes about one hour.
The street address is Foxfire Mountain, 3757 Thomas Lane, Sevierville, TN 37876. The web address is http://foxfiremountain.com/americas-longest-swinging-bridge/. This article was taken from their website.
Gatlinburg has now built a swinging bridge which is even longer than this one.
