From the Archives: Construction through the mountains of northwestern Arizona

By Caroline Carpenter / ADOT Communications

We're throwing back to the mid-'60s and construction of Interstate 15 in the far northwestern corner of Arizona. The 29-mile stretch traverses very rugged terrain through the Virgin River gorge. This photo gives you a good perspective of the steep mountains compared to the vehicle parked in path of the highway under construction.

It’s safe to say things have changed since 1912 when the Arizona Highway Department was first established. But you don’t just have to take our word … we’ve got plenty of pictures to prove it. We combed through our archives and decided to periodically post these photos from the past in a blog series we’re calling, “From the ADOT Archives.”
