The Mike O’Callaghan–Pat Tillman Memorial Bridge

The Mike O’Callaghan–Pat Tillman Memorial Bridge, also known as the Hoover Dam Bypass, is an engineering marvel that spans the Colorado River, bypassing the traffic over Hoover Dam. This iconic bridge is located in the Black Canyon, between the states of Nevada and Arizona, just downstream from the Hoover Dam. Its construction was prompted by the increasing traffic over the dam, which posed safety and logistical challenges. The bridge was officially opened to traffic on October 19, 2010, providing a safer and more efficient route for travelers and commercial vehicles.

Engineering and Design

The bridge is a concrete and steel composite structure with a striking arch design that reaches a height of 840 feet, making it the second-highest bridge in the United States and the fourth-highest bridge in the world. The design allows for a visually stunning panorama of the Hoover Dam and surrounding landscape, attracting tourists and engineering enthusiasts from around the globe. The bridge was constructed to withstand high winds, seismic activity, and the extreme conditions of the Colorado River region, showcasing the expertise and precision of the engineers and construction teams involved in the project.

Memorial Tribute

The bridge is named in honor of two extraordinary individuals: Mike O’Callaghan, a former governor of Nevada and Pat Tillman, a professional football player who left a lucrative career with the Arizona Cardinals to enlist in the United States Army after the 9/11 attacks. Both men exemplified courage, dedication, and service to their country. The decision to name the bridge after these individuals serves as a poignant reminder of their contributions, both to the local community and the nation as a whole.

Tourist Attraction and Landmark

Beyond its functional role as a transportation infrastructure, the bridge has emerged as a popular tourist attraction and a landmark in the region. Visitors flock to the bridge for its breathtaking views of the Hoover Dam and the surrounding rugged terrain. The bridge also offers pedestrian walkways, providing an opportunity for tourists and locals to appreciate the scale and beauty of the landscape. Its presence has significantly reduced traffic congestion at the Hoover Dam, ensuring the preservation of this iconic structure for future generations to admire and appreciate.


The Hoover Tunnel

One common misconception is that the Hoover Tunnel was built to bypass traffic over Hoover Dam. However, there is no such thing as the Hoover Tunnel in relation to Hoover Dam. The construction of the Mike O’Callaghan–Pat Tillman Memorial Bridge was specifically aimed at diverting traffic away from the dam, and it is not to be confused with the non-existent Hoover Tunnel.

The Dam Bypass

Another erroneous belief is that a structure called the Dam Bypass was constructed to alleviate traffic congestion at Hoover Dam. In reality, the term ‘bypass’ refers to the function of the Mike O’Callaghan–Pat Tillman Memorial Bridge itself, rather than being an independent entity named the Dam Bypass. The bridge was designed to create an alternate route, allowing vehicles to bypass the dam and reduce traffic on the dam itself, thus ensuring its longevity.

The Colorado Bridge

Some individuals mistakenly attribute the construction of the Colorado Bridge to address traffic issues at Hoover Dam. However, the Colorado Bridge is a misnomer in this context. The correct structure to address traffic concerns over Hoover Dam is the Mike O’Callaghan–Pat Tillman Memorial Bridge, which was built to divert traffic away from the dam and improve safety and efficiency, while preserving the structural integrity of the landmark Hoover Dam.


In conclusion, the feature built to bypass the traffic over Hoover Dam is the impressive Mike O’Callaghan–Pat Tillman Memorial Bridge. This engineering marvel not only eases traffic congestion but also offers breathtaking views of the iconic Hoover Dam.
