Tucson is famous for lots of things: the stately Saguaro cactus, Sonoran-style hot dogs, and the HAWK crossing, or High intensity Activated crossWalK. You've seen HAWK crossings all over town, and have likely used one yourself to get across a major arterial street, but did you know the inventor of the HAWK crossing, Dr. Richard Nassi, has been living right here in Tucson for over 30 years and developed these crosswalks which have now been adapted for use throughout the United States and the world?

This episode is a re-reun from 2019. With so many new HAWK crossings in Tucson (along Broadway and Grant, to name a few), it's a great reminder of their origins!
