road's visual impact, at increased cost. With Goodwin's resignation, Vint's proposal became the preferred alignment. The entire project was finally opened from end to end in 1933, at a cost of $2.5 million. The western terminus of the road is at U.S. Route 2 in West Glacier, Montana. The eastern terminus is at U.S. Route 89 in St. Mary. The two-lane Going-to-the-Sun Road is quite narrow and winding, with hairpin turns, especially west of Logan Pass. Consequently, vehicle lengths over the highest portions of the roadway are limited to no longer than and no wider than between Avalanche Creek and Rising Sun picnic areas which are located many miles below Logan Pass, on the west and east sides of the pass, respectively. Vehicles over in height may not have sufficient clearance due to rock overhangs when driving west between Logan Pass and the hairpin turn called the Loop. The speed limits are in the lower elevations and in the steeper and winding alpine sections. Repairs The road is one of the most difficult roads in North America to snowplow in the spring. Up to of snow can lie on top of Logan Pass, and more just east of the pass where the deepest snowfield has long been referred to as the Big Drift. The road takes about ten weeks to plow, even with equipment that can move 4,000 tons of snow in an hour. The snowplow crew can clear as little as of the road per day. On the east side of the Continental Divide, there are few guardrails due to heavy snows and the resultant late-winter avalanches that have destroyed protective barriers. The road is generally open from early June to mid October, with its latest opening on July 15, 2022, marking the record for the latest opening since the inaugural date of July 15, 1933. A restoration project by the National Park Service and the Federal Highway Administration has been repairing road damage from many avalanches and rock slides over the years. The repairs, which started in the 1980s and continue to the present day when weather permits, include fixing retaining walls, replacing the original pavement with reinforced concrete, and work on tunnels, bridges, culverts and overlooks. Buses 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
