|Location:||Great Smoky Mountains National Park, Tennessee|
Route 441 traverses the Great Smoky Mountains National Park from the Sugarlands Visitors’ Center near Gatlinburg, Tennessee to Cherokee, North Carolina. Also known as Newfound Gap Road, the road is two lanes of some of the most heavily trafficked road in the National Park, especially in summer and fall seasons.
In Fall 2012, heavy rainfall in the area caused a portion of the roadside embankment about two miles east of Newfound Gap Overlook to cave in and slide down the mountainside. Barge Waggoner, already in a long-term relationship for surveying services with Kimley-Horn Associates for the National Highway Administration, provided 3D surveying of the slide area for purposes of emergency stabilization and repair. By using 3D laser scanning technology, Barge Waggoner was able to quickly provide accurate measurements in an area where safety and accessibility were significant constraints.
