Well this looks awesome...and scary! The country's longest pedestrian bridge just opened at SkyLift Park in Gatlinburg, TN, just a few hours away from Charlotte. The bridge stretches 680 feet over a valley and reaches 140 feet above the ground at the midpoint of the bridge. There's even a set of glass-floor panels in the middle of the bridge. SkyLift Park is open year-round and tickets can be purchased here.
