Just about every town has a “0” point for its street addresses. In Duluth, that would be the corner of Lake and Superior, right? 1 E. Superior, 1 W. Superior, 1 N. Lake, etc. The lower the address number, the closer it is to the zero point. And in general, there are imaginary lines that spread out from that point, dividing addresses into north-south, and east-west.
That all works out well in Duluth on the main grid of streets – downtown, West End, West Duluth, Lakeside… but then it starts to get odd.
