Greenbrier Road Sections Temporarily Closed for Bridge Replacement.
Ramsey Cascades Trail, Porters Creek Trail, and Backcountry Campsite 31 will be closed during the work until March 26, 2021. Old Settlers, Brushy Mountain, and Grapeyard Ridge Trails will remain open, however hikers will have no access to these trails from the Greenbrier area during the closure.
The closure will allow work crews to replace the Ramsey Prong Road bridge. Crews will be operating heavy equipment along the roads and will be using pullouts for staging construction materials. This work is part of a larger Federal Highway Administration project to replace seven bridges and repair seven others across the park.
