The Longest Tunnel In Arizona Has A Truly Fascinating Backstory
Arizona is home to many a tunnel, both natural and manmade. Papago Freeway Tunnel, located on Interstate 10 in Phoenix, has quite an interesting backstory. Despite being the longest tunnel in Arizona, it isn’t technically a tunnel at all—and not only that, but Phoenix residents were opposed to its construction anyway! Here’s everything you need to know about it:

Extending from North 3rd Avenue to North 3rd Street, the tunnel sits directly below Margaret T. Hance Park.
Not only that, but it's also the 42nd longest in the entire U.S.
According to the Arizona Department of Transportation, or ADOT, it's a series of 19 side-by-side bridge underpasses. However, locals began using the term "tunnel," so it was incorporated into the name.
Voters struck down the original plan to build it in 1975, and it wasn't until four years later that the proposal finally passed. The structure was opened to vehicular traffic in 1990—the open house attracted 300,000 people, despite its unpopularity in the beginning.
These were designed to be an express transit terminal for city buses; however, Phoenix was unable to secure enough federal funding to complete the project.
Each tube can accommodate up to 16,000 vehicles per hour, for a total of 225,000 per day.
It's a pretty special place!
