The bridge in the photo is not the Jefferson st. Bridge. It's the Jackson St bridge. There are only 2 bridges that are 2 lanes in the city. The other is McDonough and the one in the photo is not that one because the traffic light is positioned farther east due to the widening of the river before the locks. Jefferson St. is a eastbound only, 3 lane bridge. This one is 2 was and about 5 blocks north.
This is the Jackson Street bridge in Joliet, Illinois. The McDonough Street bridge is a two lane bridge too but is painted blue and has overhead arches before entering the span - just like the Cass Street bridge, only that bridge is a three lane bridge. I was born and raised in Joliet. Go to the website for Historic Bridges of Michigan and Elsewhere and you'll see great pictures of all the bridges in Joliet!

This is actually the McDonough Street Bridge. The Jefferson Street Bridge is a 3 lane one way bridge. McDonough Street is a 2 way 2 lane bridge which carries US Routes 52 and 6 over the Des Plains River.
My Father, and his before him, worked for MVSS. Thank you for posting the plaque image. That's a great bit of nostalgia.
