Glacier National Park, Montana, plow crews have reached the Big Drift, the final stretch of snow blocking Going-to-the-Sun Road, and are simultaneously working to clear the Logan Pass Visitor Center, park officials confirmed this week, marking a critical milestone in the Going-to-the-Sun Road 2026 opening season.
John Lucke, the acting chief of facility management for the park, delivered the update during a public outreach meeting Monday night in Kalispell, reports Hungry Horse News. While crews are now tackling the last major obstacle on the 50-mile alpine route, Lucke cautioned that the road will not open to the public for several more weeks.
The Big Drift is a one-mile stretch of road just east of Logan Pass where wind-driven snow regularly accumulates to depths of 50 to 80 feet each winter. Crews working from the east and west sides of the park converge at the drift each spring, joining forces to cut through the towering snowbank and reconnect the road across the Continental Divide.
Going-to-the-Sun Road 2026: Rockfall, Avalanches, and a Buried Bathroom
Lucke cited rockfall and avalanches as the primary obstacles this season, challenges that crews face every year. Windstorms over the winter also brought down a significant number of trees along the route.
A major avalanche struck Big Bend this year, burying the bathroom facility there. The structure, which is built into the mountainside and engineered to withstand a slide, remains buried. However, one of the barrier poles designed to prevent vehicles from reversing into the building was ripped out and swept down the hillside.
The road also sustained structural damage. Roughly 135 feet of rock wall was swept away in a section known as the Slopes. Permanent repairs will follow later in the season; the park will install jersey barriers as a temporary fix in the interim.
How a Record Mild Winter Shaped This Season’s Plowing
Spring plowing on the Going-to-the-Sun Road and other park roads began April 1 this year. The winter of 2025–26 has been relatively mild, with lower-than-average snowfall in the valleys, allowing crews to make faster progress through the lower elevations. Snow was largely absent from the road until crews reached the high country.
The average opening date for vehicles to travel the full 50-mile corridor is June 11, though that figure has trended later in recent decades. The road has not opened to vehicles in May since 2005.
Who Can Travel the Road Right Now
Motorists can currently drive the road as far as Avalanche Creek on the west side. Hikers and bikers may travel beyond that point, subject to where and when road crews are operating. Signs are posted prominently along the route.
Park officials warn that traveling beyond established closures can result in a significant fine.
Visitors can monitor road conditions and plowing progress through the National Park Service. Real-time updates on the Going-to-the-Sun Road are available at nps.gov/glac. Text alerts are also available by texting GNPROADS to 333111.
