M-102 (Michigan highway) [SEP] In surveying
8 Mile Road is also known as Base Line Road, for it was used to set the baseline for the Public Land Survey System in Michigan. The system helped bring order to county boundaries, which had often been set in other states by geographic markers such as rivers, hills, and trees, and were therefore rather irregular. Today, the baseline forms the northern or southern boundary of many southern Michigan counties.
