Going-to-the-Sun Road Rehabilitation Project

The Going-to-the-Sun Road Rehabilitation Project

For information on travel restrictions and trail closures related to the Reynolds Creek and Thompson Wildland Fires, please refer to the following websites:

Going-to-the-Sun Road Construction Notice - 33 miles of the Road will be closed to public travel on Monday morning October 19, 2015 between the Avalanche Developed Area and the St. Mary Campground ( just passed the closed visitor center at the foot of St. Mary Lake). The "Alpine segment" of the Road, including Logan Pass, will not be accessible for the remainder of the season.

Fall hiker-biker access through the east and west closure points (Avalanche and St. Mary) will be allowed when construction and Glacier National Park roadway maintenance activities are not being performed. At this time we do not anticipate evening or weekend work.

Due to fall and early winter weather, visitors should be aware that closure points can often change and they should contact Glacier National Park for updates.

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.

For the most up to date park road closures and travel information related to the Going-to-the-Sun Road project, call 1-406-888-7800 or visit the Glacier National Park Current Road Status website.
