I had noticed during my travels this year that RWY 9L/27R at DTW has been closed for the better part of the year, if not longer. I am just wondering why this runway has been closed?
I realize that RWY 9L/27R intersects three (4R/22L, 3L/21R, 3R/21L) of the four parallel runways that are normally used, and thus would require special operations on those three including RWY 9L/27R itself. I also realize that there are probably special spacing/timing requirements for RWY 4L/22R if 9L/27R were used.
It doesn't appear that RWY 9L/27R is under construction, either. It seems to be used only as a 200' wide E-W taxiway. I also noticed that although the RWY isn't in excellent condition, it is certainly not in bad condition.
Are there any plans to ever re-open this runway, and if so, when might it be opened? What is the usage history of this runway? If it is not going to be re-opened, will there ever be at time where it is only marked as a taxiway, thus effectively making RWY 9R/27L be RWY 9/27?
