The National Park Service will begin construction activities addressing infrastructure needs in the southern half of the Moose-Wilson Corridor beginning in the spring of 2022.

All work will preserve the rustic character of the corridor and provide high-quality visitor opportunities including wildlife and scenery viewing. Work will be completed in phases, with the first phase implemented in 2022-2023, the second phase in 2024-2025, and additional phases designed and implemented in the future.

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.

A Record of Decision for the Moose-Wilson Corridor Comprehensive Management Plan Environmental Impact Statement was approved in 2016.

The Federal Highways Administration is overseeing the project in partnership with the National Park Service.
