National Park Service



Zion is home to one of the greatest engineering feats of modern times. In 1909, Zion was virtually inaccessible to visitors because of poor road conditions and limited railway. Once Zion became a national park, people wanted to explore it. To make this possible, construction began on a 25-mile stretch of road to connect Zion to the Grand Canyon and Bryce Canyon. Completed in 1930, the Zion-Mt. Carmel Highway and Tunnel is a must see. The 1.1-mile-long tunnel cuts through the vertical sandstone cliffs of Zion, blends in with the surrounding landscape and includes windows to provide views of Zion Canyon. When the tunnel opens up, drivers are left in awe of the spectacular beauty.
