TUCSON, Ariz. (KGUN) — Navigating Tucson traffic can be a headache, but at least the city is laid out in a grid. Streets run east and west, and avenues run north and south.

But what about 'stravenues'?

We take an Absolutely Arizona trip down memory lane to find out about these diagonal streets unique to Tucson.

"You kind of look at Cherrybell Stravenue right there, and it still just looks a little off," said award-winning Tucson historian David Leighton. "It's just not something you see very often."

"It's kind of diagonal," explained Leighton. "It's kind of a street and kind of an avenue at the same time."
