I do recall some of my summer vacations during childhood, travelling with my family in a motorhome from my hometown of LA to Dallas-Fort Worth. My dad would usually take I-10, and inexplicably had exit that freeway just passed of the city of Buckeye in Arizona, probably closer to what is now the Goodyear-Avondale area. He took Buckeye Road east all the way to I-17 just west of downtown Phoenix and continued the journey.
Coming from a city (Los Angeles) where there were freeways everywhere, to a major city where an interstate stopped before entering the city limits was perplexing to my childish mind.
Road Guy Rob breaks it down and talks about a time when the city of Phoenix had a major freeway problem.
