Milwaukee Road built Z-2 in 1902 to provide rail service for the heavy industry that was on the island for a significant part of the 20th century. As my daughter drove me East along North Avenue, I grabbed these pictures. Chicago Terminal Railroad uses this rail so infrequently (video1, video2) that this bridge is now shared with pedestrians and bikes. The author of the first video extracted a still on Flickr of a single empty lumber car heading back to C&NW yards for interchange. That is because the only remaining rail-served customer on Goose Island when I took these pictures was a lumber yard near the south side of the island. Since then, that lumber yard quit using rail service. The bridge was rehabilitated in 2009, so hopefully it will remain as a pedestrian and bike crossing.
Unfortunately, every time I lean over a rail to take a picture, it comes out crooked. Nonetheless, you can see this is a bobtail swing bridge. That is, the pier is on a bank and a 140-ton counterweight leveraged by an overhead offset span is used to balance the 120-foot span over the river. You can see some of the 40 wheels that allows the bridge to turn on the pier.
A view of the offset span from inside the bridge. The cars are on North Avenue, and it is always four lanes of bumper-to-bumper traffic. One of the videos shows a crewman had to get off the engine to stop that traffic because a loud horn and bit locomotive was not intimidating enough to convince the drivers that they should yield to the "train." (It had just two cars.)
Most of the factoids in this sign I have incorporated into the narration. At the bottom of this posting is the detail in the lower-right corner of the sign. They should have used a blacker ink for the sign.

(For future reference, the video shows more territory covered by the Chicago Terminal "train.")

Here is my photo from the early 90's with the bridge tenders shack still intact. http://chicagoswitching.com/.../Akzo-Salt-Soo-Line.../...
Dennis DeBruler And back when the train had more than just lumber cars.

Cherry Ave bridge in Chicago, IL, connecting Goose Island to North Ave. An asymmetrical “bob-tail” swing bridge, it was originally built by the Milwaukee Road. In 2009, it was restored and used as a shared pedestrian and railroad bridge. In 2018, the Chicago Terminal Railroad ceased operations.
Bill Smotrilla This is a great video of how they operate that bridge before they did some repairs to it. Really Old School. https://www.youtube.com/watch?v=D-URgBbzMps
Bill Smotrilla Oops,. different bridge, but similar type.

Hard to believe that this shot is almost 5 years old.

Rob caught a clear view across the road as the private rail car Caritas was being pulled off the island.
Mike Mihaly Janusek posted several photos of the bridge.
