This is like the supposed "railroad historic district" that the feds required the Met Council to study the impacts from Southwest LRT construction. This "railroad historic district" consists of gravel pits, a freeway viaduct, and a crumbling retaining wall*.I'm sorry, but the notion that the sloped wall on the south side of the Midtown trench is somehow sacrosanct makes a parody of historic preservation.
Just because something is old does not give it intrinsic veto power over any subsequent improvement.
*The retaining wall supported a railroad trestle, and if the trestle were still there then I could see the merit of studying impacts to that, but it was torn down decades ago.
