The Mike O’Callaghan–Pat Tillman Memorial Arch Bridge, also known as the Hoover Dam Bridge, spans the Colorado River, connecting Nevada and Arizona in the United States.
This bridge has a a length of nearly 580 meters and one 263 m high, approximately. The The arch is about 320 meters long. One of the biggest challenges the workers faced during construction was the strong winds or the high temperatures in the area. The most commonly used material was concrete and the following were used complex crane systems.
The bridge piers were constructed using precast concrete, since this option offered numerous advantages, such as optimizing construction time. Approximately 400 precast concrete blocks.
To construct the arch—which was built from both sides of the bridge simultaneously—it was necessary to erect temporary towers, from which a series of stays extended to support the concrete segments that formed the arch. Once the arch was completed, the stays and towers could be removed, since The arch was able to support itself.
Construction of the bridge began in 2005 and was completed in 2010. The purpose of its construction was to alleviate traffic between the states of Nevada and Arizona by expanding U.S. Route 93, reducing the risk of accidents.
The investment required to carry out this impressive engineering project was $240 million.
