People have built bridges for hundreds of years to reach the other side of chasms that are too large. Did you know that the very first arch bridge, called Arkadiko Bridge, dates back to the 13th century? Here at A-Z-Animals, we know how lengthy Arizona bridges can get. There are more bridges we can learn about, too! Let’s explore some of the other longest bridges in Arizona below.
1. Mike O’Callaghan–Pat Tillman Memorial Bridge
Between Arizona and Nevada, a little over five miles from Boulder City, you’ll find the Mike O’Callaghan–Pat Tillman Memorial Bridge. This concrete and steel bridge is almost 900 feet above the Colorado River! It is a feat of engineering that only took about five years to complete. The bridge has two namesakes. Mike O’Callaghan is a former governor of Nevada, and Pat Tillman is a professional football player and army veteran killed in action. This bridge was crucial in the Hoover Dam Bypass project as it rerouted US 93 from its previous path along the top of the Hoover Dam. The dangerous route was notorious for hairpin turns and blind curves before the rerouting took place. The concern for pedestrians and tourists and the dam’s integrity should there be a car accident drove the decision for this change.
2. Glen Canyon Dam Bridge
Not only is the Glen Canyon Damn Bridge one of the longest in Arizona at 1,271 feet, it’s also one of the highest bridges in the United States. Completed in 1959, it’s over 600 feet, so cross if you dare! This concrete bridge crosses the Colorado River, and behind the bridge sits the enormous Glen Canyon Dam. Construction of the dam began in 1956 and would last until 1963. They made the bridge by constructing two cableway towers on either side of the canyon. Workers brought sections of the bridge in, lowered, and held back by steel tieback cables. In total, the bridge came in at just 5 million dollars! Due to the influx of workers for the dam’s construction, a town sprang up called Page!
3. London Bridge
The next bridge was built in the 1830s, with its first life in London, England! It originally crossed the River Thames before its purchase from the City of London by Robert P. McCulloch. He bought and transported the exterior granite blocks back to the United States. These 10,276 blocks were first shipped to Long Beach, CA, then trucks transported them the rest of the way. Then, they used these blocks to create a brand new bridge in Lake Havasu City. The five arches create a beautiful and prominent architectural choice for the area. At 930 feet, pedestrians enjoy coming to this bridge to take pictures or for various events. The bulk of the bridge uses reinforced concrete, so it’s incredibly sturdy.
4. Navajo Bridge
This bridge is famous for a reason! These twin steel arch bridges cross the Colorado River in the Grand Canyon National Park in Arizona and are worth visiting. It cost nearly $400,000 to build and was a crucial link for transportation between Utah and Arizona. At 909 feet long and over 400 feet tall, this bridge has a vibrant history. Initially, settlers had to use a ferry to cross the point, which wasn’t entirely safe. The first bridge in this area was from 1927, but with the creation of automobiles, experts noted the area needed a safer way to cross. After years of traffic jams and accidents, officials realized they needed a better solution. So, they built a second bridge just beside the original one!
