Phoenix, with N-S numbered streets and aves. And, Chicago with #'s on south side. North and West side natives learn names/grid, while newcomers call the named major arterials, "XX00 north/west".
Those "xx00 North" coordinate names you see in places like Chicago and Phoenix are in fact the actual (and only) street names in a lot of cities in Utah and eastern Idaho. I believe SLC is the biggest city that uses such a system as its primary street naming method.
Salt Lake proper has a different grid in the northeast quadrant, with numbered avenues and lettered streets, that doesn't quite match up with the rest of the city. (It was developed much later than the downtown area.) Also, most of its off-block streets have names (generally Street or Court north-south, and Avenue or Place east-west). My grandparents lived at 1076 South Fifth (500) East (the street signs used to have both), and Denver Street is the first street to the west, while Herbert and Harvard avenues are the streets to the north and south.
Yeah, but all of the named streets will have the coordinate number on the signs (
example), and major named streets are so few and far between that it's not that hard to memorize where the few big ones are.
The Street/Avenue directionality in SLC proper is pretty obvious but I'd never noticed the Court/Place pattern in all my years of living in Utah. Now that I'm looking for it, though...
But in Salt Lake County the blocks aren't uniform. Downtown it's 6 2/3 blocks per mile. Going north there isn't much city left, so I don't know what they do. Going east maintains 6 2/3, with State (which shifts over a block), 7th, 13th, 20th and 27th eventually following section line roads. South transitions to 8 blocks per mile following section lines, but it's not uniform. West starts at 6 2/3, but retroactively jumps to 8 following section lines at 32nd. And then there's the Avenues in my previous post.
Do non-uniform blocks matter on that scale, though? As long as block numbers count up in the same directions continuously and stay roughly the same distance, they serve their navigational purpose. The varying length of a mile depending on whether you're on the old SLC downtown or section-line grids in various parts of the valley is simply an intellectual curiosity - nobody is going to be confused that a "block" might be 0.125, 0.142857, 0.15, or 0.166667 miles long.
The Avenues...yeah, their grid is a little off from the main grid, but going with 50 units=1 Avenues block is far simpler than trying to apply the rest of the city's grid up there. And because 2nd Ave/North Temple both connect as 100 North and there's no road into that neighborhood further north, the resulting discontinuity only matters along South Temple, where the difference only gets more than 100 units at the very east end. It would make more sense if A St. had been 250 East instead of 200, but meh.
