The Hoover Dam bypass bridge is [the following]:
- The highest and longest arched concrete bridge in the Western Hemisphere.
- The second-highest bridge of any kind in the United States and 14th in the world.
- The world’s tallest concrete columns of their kind.
But what sets the bridge apart most of all is the setting.
It is [built] 890 feet above the … Colorado River, wedged between rock cliffs that form Black Canyon, with commanding views of Hoover Dam and Lake Mead.
The four-lane bridge near Boulder City, Nev., was dedicated Thursday, just two weeks after the 75th anniversary of the dam’s opening ceremony. …
The first study recommending a bypass was written in 1968, and over the years, 27 more studies followed. Yet it wasn’t until March 2001 that the Federal Highway Administration approved the plan.
Full funding would materialize only after Arizona, Nevada and various federal agencies agreed to split the cost. …
The terrorist attacks in September  quickly made it clear that Hoover Dam wasn’t just a traffic bottleneck and safety hazard but also a target.
Commercial traffic was immediately [permanently] banned from U.S. 93 across Hoover Dam, forcing [commercial vehicles to take] a 75-mile detour. The urgency to build the bridge accelerated.
Work on the $114 million bridge started on Valentine’s Day 2005.
The bridge and the new stretches of U.S. 93 leading to it will open to traffic this week. Combined, the projects came in within the $240 million budget. …..
Congress had designated the name of the bridge in a 2004 transportation bill. It honors two people from the states that the bridge connects. Pat Tillman is the Arizona Cardinals linebacker who joined the U.S. Army after the Sept. 11, 2001, attacks and was killed by friendly fire during combat in Afghanistan. Mike O’Callaghan was a two-term Nevada governor and decorated Korean War veteran.
A public celebration was held Saturday.
“The view is spectacular,” said Mike Hoover, a 62-year-old from Phoenix whose father’s name is Herbert Hoover. “The view is spectacular. People are really going to enjoy this.”
Denver resident Mike Capps, 64, has relatives in Kingman, Ariz., and visits them often. “We’ve been watching this bridge being built for the last eight years,” he said. “We made the trip just for this. Just to be a part of it.”
Views from cars crossing the dam will be partly obscured by a barrier. But pedestrians are allowed to cross on the upstream side. From there, they can look straight down through the railing at the rocks and river far below.
They also get a new perspective on the dam.
Studies from 2001 showed a motorist will save an average of 17 minutes when crossing from one side of the canyon to the other. On busy holiday weekends, the time savings could be more because the bridge eliminates tourist travel congestion and security checkpoints that have caused two-hour delays at the dam. …..
As the bridge [was being built], the 1,200 workers and 300 engineers on the project found inspiration a quarter-mile upstream.
“If any one of us had a day when we felt tired or rundown or in doubt, working in the shadow of that dam really helped,” project manager Dave Zanetell said.
“Hoover Dam was the greatest engineering accomplishment in our nation’s history,” he said. “We had an opportunity to be as great for our generation.”

5. What is the official name of the bypass bridge? Explain.
- After the Sept. 11, 2001 attacks, the bridge, which connects Nevada and Arizona, was commissioned to take truck traffic away from the dam to mitigate the risk of a potential bombing, which would cause a huge catastrophe as Hoover Dam provides a great deal of electrical power to nearby cities like Las Vegas.
- Dave Zanatell with the Federal Highway Administration told Agence France Presse that his crew of 1,200 workers and 300 engineers were not out to surpass the Hoover Dam in ingenuity. “The Hoover Dam is the greatest civil engineering achievement in America’s history,” he said.
- “Our goal was not to outdo or outshine it,” Zanatell told the news agency, adding that designers aimed to “do something that would be great for our generation and that would stand besides Hoover Dam” and become part of the structure’s legacy in a respectful way.”
- “That’s why I wanted the job – I wanted to make that project a reality,” Zanetell told the Republic. “All the great works started with 99 percent of people saying it won’t get done.” (from theepochtimes.com/n2/content/view/44362)
