The Going-to-the-Sun Road was completed in 1932 and is a spectacular 50 mile, paved two-lane highway that bisects the park east and west. It spans the width of Glacier National Park, crossing the Continental Divide at 6,646-foot-high Logan Pass. It passes through almost every type of terrain in the park, from large glacial lakes and cedar forests in the lower valleys to windswept alpine tundra atop the pass. Scenic viewpoints and pullouts line the road, so motorists can stop for extended views and photo opportunities. The road is well worth traveling in either direction, as the view from one side of the road is much different than from the other. In 1983 Going-To-The-Sun Road was included in the National Register of Historic Places and in 1985 was made a National Historic Civil Engineering Landmark.
