Going-to-the-Sun Road Rehabilitation Project

The Going-to-the-Sun Road Rehabilitation Project

The Road is currently not entirely open to public traffic. There are 12.5 miles open along Lake McDonald on the west side entering the park from West Glacier and limited access on the east side entering from St. Mary.

The annual spring road snow plowing is scheduled to begin in early April. There is no anticipated roadway construction work expected on the west side for 2015 between West Glacier and Logan Pass. Spring—summer construction work will, however, be occurring on the east side between St. Mary and Siyeh Bend, just east of Logan Pass.

The earliest the entire Going-to-the-Sun Road will open to visitor travel will be on June 19 (7:00 a.m.), weather dependent. On the east side, visitor travel will be limited to the St. Mary Visitor Center until June 5 when vehicular access to the St. Mary Campground will be allowed.

Hiker-biker access will be allowed along the St. Mary Lake during weekends and weekday evenings when the contractor is not working.

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.
