The Hoover Dam Bypass Bridge: As Amazing As The Dam

After five years and $240 million, the Mike O’Callaghan/Pat Tillman Memorial Bridge–more  commonly known as the Bypass Bride–opened to traffic in October. Here are a few interesting facts about the bridge:

  • This 1,900-foot, single-span concrete arch bridge is the largest of its kind in North America.
  • It re-routed US93, which used to go over Hoover Dam; vehicles can no longer drive over the dam to enter Arizona. You can park at some points on the Arizona side to check out the dam, but if you want to continue into Arizona, you have to use the bridge.
  • The bridge’s pedestrian sidewalk is approximately 900 feet above the Colorado River. Intrepid pedestrians will be rewarded with a spectacular view of Hoover Dam.
  • The first time anyone suggested building a bridge to re-route traffic away from Hoover Dam was in 1968.


Three days before the bridge opened to vehicles, pedestrians got all four lanes to themselves for one day. These shots from the “Bridging America” event are courtesy of Alan Stark.
