Mile Road System (Detroit)
Good overview of the mile roads in Metro Detroit.
Didn’t know about this feature with north-south addresses:
With a few exceptions, one can determine which mile roads an address is between on major north-south roads north of Five Mile/Fenkell by using the formula:
[ (first two numbers of the address) - 5 ] / 2
- Example: 34879 Gratiot Avenue [(34-5)/2] = 14.5 which indicates the address is between 14 and 15 Mile Road.
