The Zion – Mount Carmel Highway is a 25-mile (40 km) long road in Washington and Kane counties in southern Utah. The highway features a 5,613-foot (1,711 m) tunnel that follows the profile of the Pine Creek Canyon wall at a consistent distance of 21 feet (6.4 m) from the outside face of the rock to the centerline of the tunnel. The west portal is framed by a masonry facade of cut sandstone, while the east portal is a naturalistically formed hole in the rock, entered directly from a bridge. Construction proceeded using mining techniques rather than traditional tunneling techniques, starting from a stope and working outward to the portals.
