Springfield and Joplin Street Names
Springfield, too, had a pretty simple system for naming its streets, at least in the very early days. Many of the main streets were named after the principal town to which they led. For instance, St. Louis, which ran east off the square (and still does) was so named because the road ultimately led to St. Louis. Boonville was so named because it led to Boonville. Jefferson, I think, was named Jefferson not after the president but because it was the road one usually took out of Springfield to go to Jefferson City. South Avenue was so named for an obvious reason: it ran south off the square. Mt. Vernon Street led to the town of Mt. Vernon, the county seat of Lawrence County. State Street was given its name because it was a main state road that one took out of Springfield to go to Cassville and eventually to Fayetteville, Arkansas (which became known as the Wire Road). Then there is College Street, the fourth street leading off the square, which got its name because an early academy or college was located on it. No fancy explanation for how the streets got their names, at least not if you know a little about the history of the town.
When I visit a town I've never been to before, I appreciate simple systems for naming streets. New York City, for instance, is very easy to know you're way around in. All the main east-west roads are numbered streets, and most of the principal north-south roads are numbered avenues. Tulsa, Oklahoma, is another city that comes readily to mind as a place that has a simple system of street names.
