Good slednx, but most all cities/towns in UT have the grid system often called main/center streets upon which the others are based. Damn those old wagon wheel surveys didn't fit at times, as here get toward the south part of town and the east and west sides aren't straight across from each other.
You want traffic problems SLC isn't too bad its happy valley (UT county, Provo/Orem area) which will scare you, most are pointing the car not driving and doing all manner of other things while driving (eating breakfast from a bowel, reading newspapers/books/etc. shaving, make-up) and this going down the freeway at full speed.
