Arizona is rife with natural wonders, but we also have plenty of architectural marvels. The Mike O’Callaghan–Pat Tillman Memorial Bridge is one of them, rising higher than any other bridge in the state.

If you've lived in Arizona for any significant amount of time, chances are you've visited Hoover Dam at least once.

It technically has roots in Nevada, too, but one side is firmly planted on Arizona soil.
This architectural wonder isn't only impressive by Arizona standards.
