"Appraisal" is "functionally obsolete" and the sufficiency rating is just 56 out of 100. I assume that it is "functionally obsolete" because it has only one lane in each direction. (But they are big lanes, I wonder if these were two lanes in the horse-and-buggy days when it was built in 1906.)
I took the picture to capture the clever design of the counterweights. They can make gross adjustments to the weight by slipping a concrete block onto a peg near the end of the weight and they can fine tune the weight by adding blocks near the bridge. I have read that whenever Chicago adds another coat of paint to a bascule bridge, they have to add weight to the counterweights. The picture also shows the round girder on which the bridge rotates as it is raised.

I tried overexposing the shot on the left so that you could see down alongside the base girder to see its depth. But I wasn't successful. The depths would need a lot of overexposure.

Steve Corless: That building on the right in this photo used to be a company Premium Plastics, I spend a lot of time in Premium Plastics working on their lift trucks, that was an old building, death trap back in the '80s, it's abandoned now, the building that was across from Premium Plastics further east I believe was burned for the movie Backdraft in the final scene.
Jack Wells: Steve Corless The building has been renovated , all new windows put in , I think it's going to be residential.

On the left bank we see a small towboat shuffling barges for Ozinga Concrete. It has a retractable pilothouse because Chicago does not raise its bridges for barge traffic. (Unless a barge has a crane on it.)

The east leaf of the 22nd Street (now Cermak Road) bridge over the South Branch of the Chicago River in the raised position during construction on June 7, 1906. The bridge was built by the Sanitary District of Chicago (now MWRD) in 1905 and 1906 and underwent renovations in 1997 by the City of Chicago. It is the only remaining Scherzer rolling lift bascule road bridge in Chicago.
