Detroit - the Woodward Plan

There's a lot of good cartographic content on flickr. I was looking for something else on a flickr group titled The Paper Cites- Speculative and Unbuilt Structures, when I came across this image from a user who calls himself whitewall buick. It shows the "Governor and Judges' Plan" for Detroit after the1805 fire destroyed the city. This plan was based on L'Enfant's plan for Washington DC with a series of plazas and wide boulevards radiating outwards. The shaded area is what was actually implemented.

According to the poster, the remaining areas grew haphazardly because the city was not given the authority to force private landowners to subdivide their land according to the plan. Unfortunately much of the content on flickr is poorly attributed and he does not give much more information.

Here is a map the current street network (and what was ruined) from Detroit Yes! I suspect this map is a bit out of date because it does not show the Campus Martius Park (see below.)

Michigan Territory Chief Justice Augustus B. Woodward proposed a plan of hexagonal blocks with the Grand Circus as the central point.

The Campus Martius, a few blocks south of the Grand Circus, is the point of origin for Michigan's coordinate system of roads that includes the Seven and Eight Mile roads located at those distances away.

Here is a photo of the point of origin marker. Campus Martius Park has recently been redeveloped into a very popular city park with fountains, performance spaces and an ice skating rink.
