Road Construction and Infrastructure Project Work

2024 Major Construction Areas. Map of Glacier with 2 pop out areas that show lines and orange cones pointing to construction. North Fork: Glacier Drive in Polebridge. West Glacier: GTSR, Upper McDonald Creek, and Inside North Fork Road.

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 2024 there will be several road construction projects that may impact travel times within the Glacier National Park area.

Going-to-the-Sun Road
The west side of Going-to-the-Sun Road will undergo the last phase of construction work that began in May 2023. The last 2.8 miles of construction will focus on paving Going-to-the-Sun Road, starting west of Sprague Creek Campground up to North Lake McDonald Road.

Construction will resume in April 2024, and is expected to be completed in late May to early June 2024, weather permitting. Construction will cause delays along Going-to-the-Sun Road. Visitors should anticipate up to a 30-minute wait.

There are no nightime closures in the construction zone planned at this time. Any updates to night closures will be posted here. Visitors should check this page before their visit if they intend to visit at night.

Upper McDonald Creek Bridge
A bridge replacement is underway on upper McDonald Creek. The bridge provides access to the northwest shore of Lake McDonald including private homes, the Lake McDonald Ranger Station, and trailheads. When completed, the new bridge will be approximately 30 feet upstream of the existing bridge, requiring a realignment of the road approaches.

Similar to 2023, North Lake McDonald Road will be closed for the entire 2024 season at the Going-to-the-Sun Road intersection. There will be no public access, including vehicles, hiking, or biking and no parking beyond or in the vicinity of the intersection. Visitors intending on hiking the Johns Lake Loop Trail will not be able to complete the loop and will need to turn around where trail closure signs are posted. Bridge construction is expected to conclude in August 2024.

PolebridgeGlacier Drive to North Fork Entrance
Construction on Glacier Drive in Polebridge that began in 2023 will continue in 2024. Visitors to the Polebridge area should expect 30-minute delays before arriving at and departing from the park entrance. Visitors are encouraged not to drive all the way to the North Fork entrance unless they have a vehicle reservation to decrease traffic in the work zone. Updates for the construction project can be found on Montana Department of Transportation's website.

Inside North Fork Road
Grading will be ongoing throughout the summer on the road to Bowman and Kintla lakes. Operations will not disrupt travel to these destinations. Major road work between Camas and Anaconda Creek could impact hiker and biker travel

Many GlacierSwiftcurrent
Starting September 16, 2024, the road past Many Glacier Hotel at the T-intersection will be closed due to construction on the Swiftcurrent Water Distribution System and road rehabilitation. Construction will begin after Swiftcurrent Motor Inn, Many Glacier Hotel, and Many Glacier Campground are closed for the 2024 season.

Trail access will still be allowed for trails such as Ptarmigan Tunnel (and points beyond), Iceberg Lake, and Swiftcurrent Pass. However, visitors will need to park in the Many Glacier Hotel parking lot, walk to the closure point and use the horse trail to bypass construction. Signs will indicate the detour. Cars will not be able to pass through the construction zone. For best access to Grinnell and Lake Josephine Trails, start from the South Shore Trailhead at the south end of Many Glacier Hotel.

Primitive camping at Many Glacier Campground will not be available in Fall 2024 due to construction. Many Glacier Campground’s regular summer season is from early June to mid-September.

How does the free shuttle work?

The shuttle can move you along Going-to-the-Sun Road but requires flexibility.
