Mike O'Callaghan–Pat Tillman Memorial Bridge

The steel and concrete structure spans 579 meters across the Colorado River, connecting Nevada and Arizona at a height of 270 meters above water.

The bridge construction started in 2005 and concluded in 2010, replacing the previous route that ran directly over the Hoover Dam.

The bridge memorializes Mike O'Callaghan, former Nevada governor, and Pat Tillman, an NFL player who died serving in the U.S. Army in Afghanistan.

Pedestrians can access dedicated walkways for observing both the bridge structure and clear views of the Hoover Dam in the Black Canyon.

The structure contains the widest concrete arches in the Western Hemisphere and stands as the first concrete-steel composite deck arch bridge in the United States.
