The only road that passes through the heart of the Glacier National Park in Montana, the Going-to-the-Sun Road is significant for a number of reasons. This is why it has landed itself a declaration of being a National Historic Landmark in 1997, and as a Historic Civil Engineering Landmark. This Road that encompasses the Continental Divide at Logan Pass boasts of the following breakthroughs:

1. It is one of the first National Park Service projects designed to accommodate tourists riding automobiles.
2. It made seeing the Glacier National Park easier to visit, as it normally took 3-4 days to see it before the road was competed in 1932.
3. It offers tours using ?jammers? that were restored in 2001.

Before visiting the park and the Going-to-the-Sun Road, make sure to learn of the restrictions first, as there are some important rules that tourists will need to follow for safety reasons.
