Going to the Sun Road
Going-to-the-Sun Road is the only road through the heart of Glacier National Park in Montana, USA. It was completed in 1932, and it is the only road that crosses the park, going over the Continental Divide at Logan Pass. A fleet of 1930s red tour buses nicknamed "jammers", rebuilt in 2001 to run on propane or natural gas, offer tours on the road. The road, a National Historic Landmark and a Historic Civil Engineering Landmark, spans 53 miles (85 km) across the width of the park.
