The Royal Gorge Bridge is a tourist attraction near Cañon City, Colorado, within a 360-acre (150 ha) theme park. The bridge deck hangs 955 feet (291 m) above the Arkansas River, and held the record of highest bridge in the world from 1929 until 2003, when it was surpassed by a bridge in China. It is a suspension bridge with a main span of 938 feet (286 m). The bridge is 1,260 feet (384 m) long and 18 feet (5.5 m) wide, with a wooden walkway with 1292 planks. The bridge is suspended from towers that are 150 feet (46 m) high.

The bridge was constructed in six months, between June 5, 1929, and late November 1929, as a toll bridge, at a cost of $350,000. It was listed in the National Register of Historic Places in 1983. The bridge was not constructed for transportation purposes; instead, it was built with the intent that it serve as a tourist attraction, and has continued to be one of the most-visited tourist attractions in Colorado since its construction. The road is designated as Fremont County Road 3A. The Royal Gorge Route Railroad runs under the bridge along the base of Royal Gorge.

Measuring from deck to the river below, the Royal Gorge Bridge held the record of highest bridge in the world from 1929 to 2003, when it was surpassed by the Beipanjiang River 2003 Bridge. It is still the highest bridge in North America. The cable-stayed Viaduc de Millau, completed in December 2004, is the tallest bridge in the world, at 1,118 feet (341 m), measured from the ground to the top of the bridge piers. However, its deck is only 885 feet (270 m) above the River Tarn.
