I was flipping through one of my sketchbooks from Chicago and repeatedly ran into drawings I did of this lifting bridge over the Chicago River.
Located behind the Merchandise Mart, it is a freight train bridge on a deadend spur that I believe ends under the Mart. I have seen trains there but I never saw this bridge down in the 4 or so years of working within a few blocks of it. Directly across the river is a condo project, I think by Harry Weese, that responds to the angle of the bridge. It always looks like it took so much effort to keep this thing at this equilibrium, a bridge always ready to bounce, to clamber down and have trains rumble across.
