11. Royal Gorge Bridge
The Royal Gorge Bridge, completed in 1929, soars high above Colorado’s breathtaking Royal Gorge. For over seven decades, it held the title of the world’s highest bridge, standing as a testament to the daring vision and skill of early 20th-century American engineers. Suspended nearly 1,000 feet above the Arkansas River, the bridge remains a popular attraction, offering stunning views and a tangible link to the era of bold infrastructure dreams.
