The O’Callaghan-Tillman Memorial Bridge

This engineering marvel of the 21st century is the first concrete-steel composite arch bridge built in the United States, and is the widest concrete arch bridge in the western hemisphere.  The bridge was built because of several factors, including the steep grades, sharp hairpin turns, and the narrow road approaching, and crossing the Hoover Dam, plus the security worries brought on by 9/11.

The bridge was designed to be compatible with the engineering design of the Hoover Dam. The pedestrian walkway provides a stunning view of Hoover Dam, a view provided before only by helicopter, or rough climbing.

Tourists now have two engineering marvels to visit in the Las Vegas area.  One should plan a few hours to stop and visit the Hoover Dam and Bridge.  Take plenty of photos for the memories.
