Colorado had its interesting road naming/numbering conventions. These are Utah's: all the roads are numbered multiples of one hundred with a cardinal direction showing where they are in relation to whatever the "zero" streets are. So you'd have 200 North, 100 North, Center, 100 South, etc. Salt Lake City is like this, with the "Zero" being Temple Square, Mormon HQ. (Pictured: Kanab, Utah as we approach the Arizona border)
