Project Overview

As you are most likely aware, the Going-to-the-Sun Road is undergoing an extensive rehabilitation. This multi-year project is overseen by the Federal Highway Administration in partnership with the National Park Service at Glacier National Park.

After extensive public involvement in the early 2000s, the preferred alternative selected for the park's environmental impact statement directs 'Shared Use' of the Sun Road during the core summer season (mid June to mid September), weather permitting.

Weather permitting, before and after the core season of 'Shared Use' (mid June to Mid September), road work for the project will be accelerated and prevent through traffic across the entire Sun Road.
