Crossing the Cortland St. Bridge

On my weekly trips to Chicago Life Drawing class, I sometimes get off the Metra at the Clybourn stop and walk east across the Cortland St. bridge. The river is a lot narrower here than downtown, so it’s a small bridge on the east are several foundries and scrap yards, and sometimes on the river a tug (do they call them tugs?) is pushing a barge up to one of the docks. The tugs have “elevator” wheelhouses, so they can get up high to see ahead of the barge they’re pushing, or go low to get under a bridge. As I walk further east, I look to see if the doors of the Finkl foundry are open so I can watch them pouring molten steel.
