The Daily Inter Lake reports road crews have begun installing snow poles in the mountaintop section of Going-to-the-Sun Road, which is set to close on Oct. 15.
The park closes the road in sections. A construction project this year will briefly close the road at the foot of Lake McDonald to Jackson Glacier Overlook from Oct. 15-19.
Depending on weather conditions, the section between Lake McDonald Lodge and near the St. Mary Campground turnoff typically closes in mid-December.
Most concessionaire services in the park have ended for the season, but a few bus tours will continue through mid-October.
