O'Callaghan Tillman Memorial Bridge
This concrete arch bridge is the highest in America, and the best place to find vertigo-inducing views of the Hoover Dam, Lake Mead and the towering rocks of the Black Canyon. Located less than an hour’s drive from the Las Vegas strip, it was built as a faster, safer way to cross the Colorado River between Arizona and Nevada. Its open structure was designed to withstand winds, earthquakes and heavy service loads without encroaching on the views of the dam or surrounding area. The bridge is a fitting tribute to the two war heroes it's named after. Mike O'Callaghan was a former Nevada governor and Korean War veteran, and Pat Tillman was an Arizona Cardinals football player who lost his life in Afghanistan, aged 27.
