A vital artery in Phoenix's transportation network, SR 51 has an interesting history that reflects the city's growth and development. Originally conceived in the 1950s as an official offshoot of Interstate 10, as I-510, SR 51 was designed to alleviate congestion and accommodate the increasing number of residents and businesses in the area.

Members of ADOT's Motor Vehicle Division teamed up with Donor Network of Arizona and marched in the 51st Vrbo Fiesta Bowl Parade presented by Lerner and Rowe to remind everyone that registering as an organ and tissue donor is always in season and a great play for the community.

ADOT worked with the Hopi Tribe and the Federal Highway Administration on a safety project for residents of the Hopi community of Second Mesa along State Route 264 in northeastern Arizona.

Holiday cheer has landed on our overhead signs reminding travelers to drive safely (and end up on Santa’s “nice” list) in the days leading up to Christmas. 

It’s been a great year for the ADOT Blog. We published more than 140 articles, covering a wide range of topics from project progress and historical anecdotes to animal rescues and Adopt a Highway updates. Since it’s the end of the year, now’s the perfect time to count down the ten most-read blogs of 2023.

If you have a question related to Arizona roadways, who you gonna call? The answer is: It depends.

Here at ADOT, we’re happy to answer questions about highways, the Motor Vehicle Division and more. But sometimes, people call us for information that we simply don’t have access to or for something happening on a roadway that is outside our jurisdiction.
