I wish more cities would compile and publish this information.<p>I grew up in Miami that has a sort of less-structured grid system where avenues are the primary north-south roads and streets are the primary east-west roads. There's a through road every half mile, or numbering-wise every 8 streets or 5 avenues. So if you know this fact, you'll know that SW 47th ave is extremely likely to be a through road until it reaches the coast, and SW 42nd Ave is maybe a bit less likely but still probably a through road. Same with SW 88th st (main through road) and SW 96th st (probably a through road). In between these main grid streets you're on your own.<p>Incredibly, most people I speak to who live there do not realize this! As far as I can tell, it's not explained anywhere on the county or city website, at least that I can easily google. It makes getting around the city's surface streets much, much easier, but it's just not common knowledge.
