Mile Roads' other names?

[Michael Hojnacki]

Campus Martius has a medallion marking the starting point, I am not sure if anyone mentioned this.

Detroit streets are laid out to three different grid systems. Downtown aligns on ribbon farms oriented on the Detroit River. The east side aligns on ribbon farms oriented on Lake St Clair. Later annexations align with the Northwest Ordinance Survey grid.

The Boynton and most of the Oakwood Heights neighborhoods are aligned on a fourth grid, this one more ribbon farms oriented on the Detroit River, just a different angle to keep the orientation to the river. This grid system extends east into River Rouge and Ecorse, south into the northern halves of Lincoln Park and Allen Park and west into Melvindale, south central Dearborn and a single street in Dearborn Heights.

Yes, the survey marker in Campus Martius is a former survey monument. It was used for surveying a portion of the platted land in Detroit.

However, it is not a survey monument that was put in place for the US Public Land Survey System that established the 'Mile Roads' around here.

But, that's not to say the two are unrelated. When the surveyors established the baseline for the Michigan survey, they wanted it to be north Detroit. Of course, Detroit was just a village on the Detroit River at the time.

Two web sites that goes over how the grid system was established in Michigan:

C. Albert White compiled the notes of the surveyors in his book 'Initial Points of the Rectangular Survey System', https://www.amazon.com/Initial-point.../dp/B0006QL97G.
