Going-to-the-Sun Road has been undergoing a major rehabilitation project since 2007. Visit the Federal Highway Administration's project page for construction information, photos, and mapping.
This year will bring the final phase of the Going-to-the-Sun Road rehabilitation project, including 14 miles (22.5 km) of parking and signage improvements from the park boundary in West Glacier to beyond the Avalanche developed area. Paving improvements will occur from the park entrance station to the intersection with Apgar Loop Road on Going-to-the-Sun Road. Beginning September 5, visitor traffic will be managed through the area under traffic control.
One lane closures with a cumulative delay of no longer than 30 minutes may occur throughout the late-summer and fall.
In October the section of Going-to-the-Sun Road from the four-way intersection, near Apgar, to Logan Pass will be closed to vehicles, bicycles, and foot travel. Access to Logan Pass from the east side of the park will remain available, weather permitting, until the road is closed for the season in October 16.
