Why Going-to-the-Sun Road Was Never Built for Modern Traffic

Going-to-the-Sun Road looks like the perfect mountain drive—but its breathtaking scenery comes with narrow lanes, blind curves, stone walls, and steep drop-offs. Built in 1932 for a much quieter era of travel, the road was designed to provide access to Glacier National Park’s alpine landscapes, not to handle today’s RVs, rental cars, and heavy summer crowds. Discover how engineers shaped the road around the mountain, why its tight design was intentional, and how modern traffic is pushing this historic route beyond what it was built to handle.
