The Bridge Across
The Mike O'Callaghan–Pat Tillman Memorial Bridge as seen from Hoover Dam. This bridge was built to handle the large number of visitors to the Hoover Dam. The Hoover Dam is one of America's modern engineering wonders. It was built by thousands of workers during the Depression years in extremely harsh conditions and stands as a testimony to human ingenuity and labor.
