Going-to-the-Sun Road Rehabilitation Project

Latest Construction Update

The Going-to-the-Sun Road (Sun Road) is fully open for the 2018 season.

The New St. Mary Entrance Station opened in June 2017 but has sustained damage from over-height vehicles. This fall the roof will be re-constructed plus some warning devices to help prevent this. The construction of a new footbridge at Avalanche is complete and the boardwalk connection to the Trail of the Cedars is being constructed this summer. The Trail of the Cedars is fully open for hikers.

The last segment of work to be issued under the Sun Road Rehabilitation effort (which began in 2007) has been awarded. Construction began in spring 2017 between the West Entrance Station and the Avalanche Developed Area (15.5 miles). This work continues this summer and into the fall. Visitors can expect a traffic delays 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 at one segment in the alpine section of the road with the installation of stone masonry veneer that was previously damaged by avalanches.

This year, visitors should be aware that October 15 is the last day that visitors will be able to drive to Logan Pass from the west side as the park Road Crew begins to winterize the road.

Please take Note: Access to Avalanche will not be available from October 15 to 19, as the contractor installs another large box culvert approximately 5.5 miles from the west entrance station. The temporary closure will be at the gate at the foot of Lake McDonald. Access to Apgar Village and the visitor center will still be available during that week. On October 20, 2018, access to Avalanche will once again open and will remain open until the gate closes at Lake McDonald Lodge for the winter.

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.
