context_page_description: 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, 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 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.
  The road is one of the most difficult roads in North America to snowplow in the spring.
context_section_description: A fleet of vintage 1930s red buses, modernized in 2001 and called Red Jammers, or simply "Reds", continue the tradition of offering guided tours along the road. The original bus drivers became affectionately known as "Gear Jammers" or simply "Jammers" since they had to jam the manual gearbox into low to safely negotiate the steepest road sections. Thirty-three of the original buses were rebuilt with flexible-fuel engines which operate mainly on propane but can use gasoline, and with automatic transmissions, making the Jammer name archaic. Modern-style shuttle buses for shorter trips and Blackfeet tour buses operate on the road as well.
