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. Prior to the construction of the road, visitors would need to spend several days traveling through the central part of the park, an area which can now be traversed within a few hours, excluding any stops for sightseeing or construction. 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, Montana on the east side of the park. Name The road is named after Going-to-the-Sun Mountain which dominates the eastbound view beyond Logan Pass. One Native American legend concerns the deity Sour Spirit who came down from the sun to teach the Blackfeet the basics of hunting. While returning to the sun, an image of Sour Spirit was placed on the mountain as an inspiration for the Blackfeet. Another story has suggested that a late-19th-century Euro-American explorer provided the mountain's name and the legend. Design Going-to-the-Sun Road, also known as Glacier Route 1 Road, is notable as one of the first National Park Service projects specifically intended to accommodate the automobile-borne tourist. The road was first conceived by superintendent George Goodwin in 1917, who became the chief engineer of the Park Service the following year. As chief engineer, the new road became Goodwin's primary project, and construction began in 1921. As the project proceeded, Goodwin lost influence with National Park Service director Stephen Mather, who favored landscape architect Thomas Chalmers Vint's alternative routing of the upper portion of the road along the Garden Wall escarpment. Vint's alignment reduced both switchbacks and the
