Looking toward the Arizona side of the Colorado River canyon.

The Mike O'Callaghan–Pat Tillman Memorial Bridge spans the Colorado River between Arizona and Nevada south of Hoover dam on U.S. Highway 93. It was built to bypass Hoover Dam making travel to Las Vegas from Kingman, AZ, and vice versa, much quicker and easier. After 9/11, the federal government restricted access to all major dams in the USA, but until the Mike O'Callaghan–Pat Tillman Memorial Bridge was built, the only way to go to and from Las Vegas on U.S. Highway 93 was to drive over Hoover Dam. Now there is one way in and out to access the bridge walkway and Hoover Dam from the Nevada side, with a checkpoint every vehicle going to Hoover Dam has to stop at. The line of vehicles can be very long waiting to get through the checkpoint. We didn't have time to drive over the dam and get photos of the bridge, and stop and walk the bridge, so we opted to walk the bridge and photograph Hoover Dam.  There is a very nice set of displays as you walk up to the bridge that explains how the bridge was built.

Welcome to Nevada.

At the center of the bridge I have one foot in Nevada, the other in Arizona.
