Belmont Avenue Bridge over North Branch

(Bridge Hunter (the map has to be wrong), Satellite)

Belmont Avenue used to be the northernmost movable bridge. The Grebe Boat Yard used to occupy the west bank between Roscoe and Belmont. The longest boats they made were part of their WWII production --- a 440' water tanker [ShipBuildingHistory, another article]

Tim Paske posted three pictures with the comment "Belmont Bridge circa 1902 looking west from Western , photo's 2-3 same place but taken in 1970. Bridge has been replaced since."

Thomas E. Zimmerman And that church is still there I believe. However I think the steeple was taken down a few years ago after being damaged in a storm.
Kody Thames Thomas E. Zimmerman That was my first thought too.

It is now just yet another steel girder bridge.

Boats docked on the North Branch of the Chicago River, looking east across the river from the west bank, just south of the Belmont Avenue Bridge on May 27, 1920. Riverview Park roller coaster structures can be seen in the background at left.
Gregory Feret: we see the structure past the bridge of an unidentified old Riverview roller-coaster. It's likely to remain unidentified too IMO because none of the latter-day park coasters had tracks that traveled out quite that closeby to Belmont ave. It is known that riverview had coasters that were demolished early on (this photo is 1920 after all) and replaced with others.

[And another view of the Riverview Park amusement ride. In the right background. We are looking at the southeast quadrant of Belmont and the river. The Grebe Shipyard was in the northwest quadrant.]

And, you can see the roller coaster structure at Riverview Park with the American flag above. Cool. Judging by the map below, that rollercoaster would be The Bobs, my favorite!
Gregory Feret: that coaster looks very close to Belmont ave, which tells me it's not a coaster at all (riverview never had any coaster so close to Belmont ave), so it very well could be a bicycle 'velocipede' racetrack structure that they did have in those early years.
