CURRENT WINTER ADVISORY MAP FOR MONTANA

GOING-TO-THE-SUN ROAD INFO:

Going-to-the-Sun Road is a scenic mountain road in the Rocky Mountains of the western United States, in Glacier National Park in Montana. The Sun Road, as it is sometimes abbreviated in National Park Service documents, is the only road that traverses the park, crossing the Continental Divide through Logan Pass at an elevation of 6,646 feet (2,026 m), which is the highest point on the road. Construction began in 1921 and was completed in 1932 with formal dedication in the following summer on July 15, 1933. The road is the first to have been registered in all of the following categories: National Historic Place, National Historic Landmark and Historic Civil Engineering Landmark. The road is approximately 50 miles (80 km) long and spans the width of the park between the east and west entrance stations.  The National Historic Landmark Nomination records a slightly shorter distance of 48.7 miles which is measured from the first main intersection just outside the park’s west entrance to Divide Creek in St. Mary on the east side of the park.
