The Going-to-the-Sun Road (Sun Road) is fully open for the 2017 season.

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.

The New St. Mary Entrance Station opened on Friday, June 23. The construction of a new footbridge at Avalanche, on the west side of the Sun Road is completed and the Trail of the Cedars is completely open to hikers. Boardwalk construction tying into the new bridge will begin this fall.

The last segment of work to be issued under the Sun Road Rehabilitation effort (which began in 2007) has been awarded, with construction beginning this spring between the West Entrance Station and the Avalanche Developed Area (15.5 miles). Visitors can expect a traffic delay(s) totaling up to 30 minutes as roadway work progresses along Lake McDonald and up to the Avalanche developed area. Later in the season work will also be occurring in the alpine segment of the road with the installation of railing at four locations where they were previously damaged by avalanches.

This year, visitors should be aware that October 8 will be the last day that visitors will be able to drive to Logan Pass from the west side as major drainage culverts will be installed at a site approximately 5 miles east of Apgar on the Sun Road. This work will necessitate a complete closure of the road on the west side of Logan Pass.

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.
