Odds are you’ve driven through the part of Interstate 10 in downtown Phoenix that dips into a tunnel.
Phoenix natives call this the Deck Park Tunnel. But that is that is not its real name, and it’s technically not a tunnel. The real name is the Papago Freeway Tunnel and it's a series of 19 bridges. Big surprise, right?
To dig in to this controversial history, listen to this episode of Valley 101, a podcast from The Arizona Republic and azcentral.com.
This episode contains clips of a video called "Soaring Sculpture" produced by Swartwout Film Productions in cooperation with the Arizona State Highway Department and the Bureau of Public Roads and U.S. Department of Transportation. Thank you to the Arizona Department of Transportation for letting us use parts of that video.
