"From Monday, July 15, 2019 to Saturday, July 27, 2019, Gratiot will be closed from Woodward to Library street. Some of the Quicken Loans folks that park underneath One Campus Martius will have their parking temporarily relocated to nearby structures due to the closure.
I can only speculate as to why the road will be closed. I don't think it will be for the One Campus Martius building, as they seem to be needing less space now that the majority of the addition is done.
My speculation is that it has to do with the Hudson's site. Fingers crossed, I'm hoping it for crane(s) to be erected on Gratiot to serve the site. Although that is really close to One Campus Martius, a major crane for the Hudson's site would more than likely be much taller than One Campus Martius."
