I asked this question on the model railroad thread, but I'll put it up here as well. Were there any NYC branchlines that bridged over the GTW anywhere in Michigan?

I don't think so, but I'm no expert. If you haven't already, check out the map menu at RRHX. They have MC (later, NYC) maps for the 19-teens through the 1930s. That will at least show you where junctions were, then look them up on google maps or live search.
