This 5,613- foot-long tunnel, the longest vehicular tunnel in the National Park System, was blasted through the towering sandstone cliffs above Pine Creek Canyon. Construction required extraordinary access through cliff-face galleries for blasting and excavation. The tunnel and the 25-mile-long highway, completed between 1927 and 1930, promoted the "NPS-Rustic" style of engineering and landscape architecture used throughout the National Park System.

Constructed: 1927 – 1930 Designated: 2011

Erected by American Society of Civil Engineers.
