The Corkscrew Bridge employed an unusual engineering technique to change elevation rapidly on a steep section of the East Entrance Road near Sylvan Pass. By 1929, when it was bypassed with a road constructed along the above slope, the increasing power and speed of automobiles had rendered it obsolete.
