Road reconstruction typically requires warmer weather. In this part of the country that means road construction overlaps with the primary visitor season of May through October.

In the summer of 2021 there will be several road construction projects that may impact travel times within the Glacier National Park area.

For a listing of roads currently open or closed please click here.

As You Approach the Park

U.S. Highway 2
Highway 2, along the southern boundary of the park, will see extensive road work between Hungry Horse, MT and the Nyack Flats area. Expect traffic delays along this route.

U.S. Highway 89
The section of Highway 89 immediately east and south of St. Mary, MT will be under construction this summer. This is the continuation of a multi-year project that has been ongoing for the last few summers. Expect traffic delays.

Inside the Park

Going-to-the-Sun Road
Vault toilets will be installed at Big Bend and St. Mary Falls between June 10, 2021 and August 26, 2021. At both locations, expect limited parking and minor traffic delays.

A trail hardening project at Lunch Creek (just east of Logan Pass) and Upper Road Camp (just west of Haystack Creek) may require traffic delays. Construction equipment will use some of the parking areas limiting available parking spaces. Logan Pass will have gates installed at the entrance and exit of the parking lot and a new shelter will be constructed at the Logan Pass Transit Stop, to help shield against inclement weather.

Guardwall work will continue this summer at various locations along the Going-to-the-Sun Road as needed.

Beginning in October, work to repair water and sewer infrastructure will require a closure of the section of road from the four-way intersection (near Apgar) to Lake McDonald Lodge. This section of road will be closed from October 1, 2021 to March 15, 2022. There will be no winter recreation access through the closure.

Many Glacier Road
Two sections of the Many Glacier Road will be under reconstruction in 2021. The section from Babb, MT to the Park Boundary and the section from the Park Entrance Station to the Many Glacier Hotel will be worked on. Expect delays of up to 40 minutes through these sections of the road. Please adjust your estimated travel time accordingly.

  • During periods of heavy visitation traffic may be stopped at Babb and entrance to the park may be held until traffic or parking congestion has cleared.
  • The Many Glacier Valley will close to all access from March 15, 2021 until May 28, 2021 and will close for the season on September 17.

Camas Road
Road reconstruction work will extend for approximately 5.25 miles up Camas Road, beginning just past the Apgar Visitor Center. Also, there will be a new park entrance station installed just past the turnoff to the Fish Creek Campground.

Inside North Fork Road
Bridge work will be ongoing on the bridges over Logging, Quartz, Anaconda, Dutch, and Camas Creeks. Access south of Polebridge to Camas Creek will be prohibited. Hikers will be permitted to access the Camas Creek Trail, just north of the Camas Creek Bridge.

Additional Bridge Work
Bridges over Lee Creek (on the Chief Mountain Highway) and Appistoke Creek (near the campstore in Two Medicine) will also undergo reconstruction work in 2021.
