The Cornelius Pass Railroad Bridge is 800 ft. (244 m) long, 90 ft. (27 m) high and has 10 ft. (3 m) footings drilled into the bedrock below the ground's surface. Completed in July 1998, this structure replaces a wooden bridge and saves a 30-mile (48-km) detour for freight trains. Because of the area's humidity and the difficulty of maintenance, hot-dip galvanizing was selected as the optimal method of protection.
