Driving in Los Angeles, California (Part 2)

Notice in the map below how 101 North becomes 170 North and 134 West becomes 101 North. It makes no sense. 101 should have continued North and 134 should have continued West and there should be no 170. This is one of the strangest highway intersections I have ever seen. Try going from 101 North to 134 East or 134 West to 101 South. It's not possible as I have shown in part 1.
