Historic Railroad Tunnel Trail

The Historic Railroad Tunnel Trail is located right below the Hoover Dam Lodge, and is accessed by a trail spur that connects to the North East corner of our property. Today you can walk or bike along the elevated railroad bed used to haul supplies and materials for the construction of the Hoover Dam. It is an easy hike, providing spectacular views of Lake Mead, Boulder Basin and Fortification Hill.

Historic Railroad TrailDuring the construction of the Hoover Dam, three segments of railroad were built. Six Companies, Inc., a consortium of six firms who built the dam, along with the federal government carved out almost 30 miles of railroad.

The first segment ran from Las Vegas to Boulder City, and was built and operated by the Union Pacific Railroad.

The second segment was built by the federal government, and ran from Boulder City down to a concrete mixing plant on the rim of Black Canyon, overlooking the dam.

Six Companies built and operated the third segment. The track branched off the U.S. Government system, and followed the base of the River Mountains and then looped eastward to a gravel plant overlooking the Colorado River. Another branch went upstream from the gravel plant to the gravel beds on the Arizona side.

The Six Companies Railroad was abandoned upon completion of the Hoover Dam in 1935. The federal government railroad was used until 1961.

In 1962, the tracks were dismantled and sold as scrap. The tunnels and trail were nominated in 1984 to the National Register of Historic Places.
