Taylor Street Bridge

(Bridge Hunter; no Historic Bridges; no Chicago Loop Bridges; Satellite, removed  in 1929 so it doesn't appear in a 1938 aerial photo either)

While researching the B&OCT bridge across the South Branch before it was straightened, I found some information on the swing and rolling bridges that used to be at Taylor Street.

Below, in the background, is the Taylor Street rolling bridge in the upright position. It appears that a dredging machine is working under it. Or is it a marine crane that is removing the center pier for the former swing bridge?

Chicago circa 1900. "12th Street Bascule Bridge." Dinosaurs of the ... top (north) bridge is no longer in use - it served the old Grand Central Station (B&O and others) at Wells and Harrison until the late 50s.
David Daruszka The boat is a tour boat of the recently completed "drainage canal". The Sanitary and Ship Canal was an engineering marvel, and the techniques used in it's construction were replicated at the Panama Canal.

Taylor Street's swing bridge would not allow contemporary (1899, 478') ships to pass. The center pier also prevented the 300,000 cubic feet of water per minute flow required to flush the river down the new drainage canal. Removal of the center pier also provided the 120' navigation channel required by the United States War Department for the Chicago River. [eBook, p 696]

The swing bridge still exists in the background of this image of the B&OCT bridge.

Looking through the bridge in the foreground, we can see the Taylor Street swing span on the right and the viaduct to the west that crossed the Pennsylvania and CB&Q rail yards south of Union Station.

"Fig 4 is a general plan of the new Taylor street rolling lift bridge The span from centre to centre of bearings is 148 feet 7 inches. The roadway from centre to centre of trusses is 20 feet in width, with a 5 foot sidewalk on each side." [eBook, p 700]

CP/ICE/Milw 2004 Scherzer Bridge over Black River in La Crosse, WI

(Bridge HunterJohn A. Weeks III, no John Marvig, 3D Satellite)

While watching the video below, I could not identify what type of drawbridge was over the Black River, even when I looked at a 3D Satellite image. It seemed to be a Scherzer rolling lift bridge, but I could not clearly identify the quarter-round rolling members, even in the photos on Bridge Hunter. But John's photo below clearly shows a rolling member. I didn't know they still built this design.

The predecessor bridge was a swing bridge. So the US Coast Guard has been successful in getting a swing bridge removed from the Mississippi River. But John explains that this channel is used by recreational boats. Commercial (barge) traffic uses the west channel. When I looked at the satellite image, it appeared the Black River was just another channel of the Mississippi River. John explains "the Black River was once a separate river in this area, but it was captured a few miles up river by the Mississippi a few centuries ago." [Weeks-#7]

Preserved/B&O 1956 Bridge #463 over Cuyahoga River in Cleveland, OH

(Bridge Hunter, Historic Bridges, 3D Satellite)

I wonder if this was the last heel-trunnion bridge ever built because it was built in 1956 when the river was widened. I noticed that Bridge Hunter and Historic Bridges disagreed on the length of the span. Then I noticed that Bridge Hunter's span length was longer than the total length. So the Historic Bridges number, 231', is the correct length.

The old "Jackknife Bridge" now in the permanent open position over the Cuyahoga River in Cleveland, Ohio. I believe it belonged to the B&O railroad.
It's nice seeing a photo of a partially open bridge because it makes it easier to figure out how the linkages work.

Until 1956, this location had a Scherzer Rolling bridge like Bridge #464. Below, #463 is in the foreground and #464 is to the left of the left smokestack.

The rolling bridge was based on the bank opposite of the trunnion bridge.

Here is another view of the bridge from underneath the viaduct the photographer was standing on.
