Mountain Roads

Jul 5, 200544m

Join our journey along monumental feats of engineering that preserved America's natural wonders while paving the way towards her future. Travel the Donner Pass in the Sierra Nevada Mountains, site of a dark chapter in US history. Today, crews use the latest technology to keep I-80 open during the worst winter storms. Enjoy the view while traveling to the summit of Pike's Peak in Colorado, inspiration for America the Beautiful. The "Going-to-the-Sun-Road" slices through Montana's majestic Glacier National Park, crossing the Continental Divide and allowing motorists unsurpassed views of mountain scenery. Outside Denver, the Eisenhower Memorial Tunnel, carved through mountain rock, united eastern and western Colorado. And the Blue Ridge Parkway, which took 52 years to complete, snakes through large, scenic swatches.
