![]() NPS Photo/J. Bonney BackgroundThe Moose-Wilson Road is a 7.1 mile-long corridor located in the southwest area of Grand Teton National Park that seasonally connects key areas of the local community, such as the Jackson Hole Mountain Resort, Teton Village, and residential areas, with the interior of the park. The narrow, winding road includes approximately 1.4 miles of unpaved surface and is highly valued for its rustic character, opportunities for viewing wildlife and scenery, and access to the Laurance S. Rockefeller Preserve and hiking trails. Project OverviewA Record of Decision for the Moose-Wilson Corridor Comprehensive Management Plan Environmental Impact Statement was approved in 2016. Documents may be found on the NPS Planning, Environment and Public Comment (PEPC) web page. As part of a multi-year planning process, the park thoughtfully evaluated options to provide the greatest amount of visitor access with the lowest additional cost and construction duration, while providing for the safety of visitors and crews during construction activities. The selected action best protects the corridor’s natural and cultural resources and retains the character of the rustic road corridor. The Western Federal Lands Highway Division is overseeing the project in partnership with the National Park Service. Frequently Asked Questions Time for outside construction is limited and summer months are the best times to accomplish work.
