They called it the "Commercial Street Bridge." It turns out, it doesn't carry that street, it goes over that street. My clue as to the location was that they are going to do lane changes near Squirrel Hill Tunnel. This video was posted Feb 24, 2026, and all of the steel work is done. They now have to add the deck. It will then be moved over to replace the concrete bridge during the outage in the Summer, 2026.
