3. Royal Gorge Bridge, Colorado

The legendary Royal Gorge Bridge in Colorado stands as an enduring symbol of human audacity and remarkable engineering excellence. Rising an astounding 1,000 feet (305 meters) above the rushing Arkansas River, it proudly holds the distinction as the highest suspension bridge throughout the entire United States.
Originally constructed in 1929, the bridge stretches an impressive 1,260 feet (384 meters) across the dramatic gorge. Its traditional wooden planks, supported by incredibly strong steel cables, offer adventurous visitors absolutely thrilling views of the distant river flowing far below. For individuals terrified of heights, the completely exposed walkway presents a genuinely formidable challenge.
Throughout the decades, the Royal Gorge Bridge & Park has continuously added exciting attractions including a comprehensive visitor center, scenic gondolas, and heart-pounding zip lines, significantly enhancing the overall visitor experience. Following a devastating major fire in 2013, the entire park underwent complete reconstruction, with the historic bridge remaining as the magnificent centerpiece, ensuring its continued safety and remarkable longevity.
