DUPLICATE BRIDGES

 

 

Duplicate Bridges are movable bridges that are identical in construction, either in the same city, state, region, or a different state. These bridges that are constructed side by side twin, triple, or quadruple spans that are exactly alike, were built for railroad traffic with different train service or the same company. The counterweights, sheaves, pulleys and drums on a duplicated vertical lift bridge are identical with the last.

Bascule bridges and swing bridges are also duplicate structures with the same exact machinery and counterweight and operate the same way as the first. In Cleveland, Ohio, they were two, twin Scherzer rolling lift bridges across the Cuyahoga River. One, used by the Newburg & South Shore railroad, was demolished http://www.flickr.com/photos/94273918@N06/8665124265/and the other, a Baltimore & Ohio railroad bridge, still remains in service.http://www.flickr.com/photos/94273918@N06/8602358655/

The Columbus Roadhttp://www.flickr.com/photos/94273918@N06/8646373360/ and the Carter road vertical lift bridgeshttp://www.flickr.com/photos/94273918@N06/8646373300/ were copied when built in 1932. Three railroad lift bridges in the state of Ohio are triple duplicates. One of them has 2 tracks, the Nickel Plate Railroad bridge a double track structure with four drums on each tower, http://www.flickr.com/photos/94273918@N06/8602516595/the Wheeling & Lake Erie railroad bridge a single track with two drum pulleys on each tower, both are in Cleveland Ohio.http://www.flickr.com/photos/94273918@N06/8602516627/ The last twin a single track is in Lorain Ohio for the Norfolk Southern railroad. http://www.flickr.com/photos/94273918@N06/9733313884/

In Chicago, there were four duplicate railroad vertical lift bridges, but now there are only three because one of them was demolished. Two rail lift bridges were used by The Lake Shore & Michigan Southern Railroad for the New York Central railroad, and two by the Pittsburgh Fort Wayne & Chicago railroad for the Pennsylvania railroad crossing the Calumet River.http://www.flickr.com/photos/94273918@N06/8604001638/

In Elizabethport, New Jersey, four quadruple duplicated railroad lift bridges used by the Central of New Jersey railroad crossing the Newark bay were demolished. http://www.flickr.com/photos/94273918@N06/8961925396/Other lift bridges like the dock lift bridges used by the Amtrak railroad in Newark New Jersey crossing the Passaic River.http://www.flickr.com/photos/94273918@N06/8720334635/ Crossing the Sanitary or Drainage canal are quadruple railroad Scherzer type rolling lift bridges crossing side by side, which are inoperable. Two bridges are operated by The Chicago Terminal Transfer and the Chicago Junction railroad, two other bridges used by the Pittsburgh Cincinnati and Chicago & St Louis railroad 8 track which in the fixed positions. http://www.flickr.com/photos/94273918@N06/9042746671/

There are three duplicated Strauss heel trunnion bascule bridges, one of them remains and two others were replaced. The first heel trunnion bridge was built in 1910 for the New York New Haven & Hartford railroad and replaced with a lift bridge in 1935 in Buzzards Bay Massachusetts crossing the Cape Cod canal,http://www.flickr.com/photos/94273918@N06/8590035570/ the second duplicate heel trunnion type was built in 1911 for the Peoria Pekin & Union railroad crossing the Illinois river at Peoria Illinois was also replaced by a lift bridge. http://www.flickr.com/photos/94273918@N06/8588935667/The remaining duplicate heel trunnion bascule bridge built in 1911 for the former New York Central Line now used by the Norfolk Southern railroad crossing the Ashtabula river at Ashtabula Harbor Ohio and remains in service, http://www.flickr.com/photos/94273918@N06/8588935733/all 3 are double track 159 foot and 4 inches with drive machinery mounted on the bascule span with the operating struts pinned fixed to the bridge tower or rear panel.

The Baltimore & Ohio railroad and the Pacific Electric railroad Strauss Heel trunnion bascule bridges are duplicated at its resemblance the Baltimore & Ohio railroad bridge is 235 foot long with 2 tracks in Chicago Illinois south side crossing the Calumet river removed in 1988,http://www.flickr.com/photos/94273918@N06/8588935777/ but the Pacific Electric railroad bridge is 187 foot long and has 2 tracks with the cable wires on the bascule span for the rapid transit built in 1912 crossing the West Basin connecting Long Beach Harbor in San Pedro to Los Angeles California and was removed in1955http://www.flickr.com/photos/94273918@N06/8589811476/.

The San Pedro Los Angeles & Salt Lake railroad Scherzer rolling lift bridge crossing the San Gabriel river in Long Beach California http://www.flickr.com/photos/94273918@N06/8986912795/is Identical of the Seddon Island bridge in Tampa Florida crossing the Garrison channel use by the CSX railroadhttp://www.flickr.com/photos/94273918@N06/8699318120/, which in 1982 this bridge was demolished.

In New Orleans Louisiana are 3 Identical Strauss heel trunnion bascule bridges crossing the Industrial canal are 117 foot with 2 roadways on the the outside with 2 tracks, Florida Avenue, Almonaster Avenue, and Seabrook bridges. The Florida Avenue Strauss bascule bridge was replaced with a vertical lift bridge,http://www.flickr.com/photos/94273918@N06/8625641200/ the Almonaster Avenue bridge will be or was replaced with a lift bridge http://www.flickr.com/photos/94273918@N06/8589598873/but the Seabrook bridge remains and only carries rail traffic and the roadways were removed due to hurricane Katrinahttp://www.flickr.com/photos/94273918@N06/8620268030/. The Seabrook (Ted Hickey) bridge is a double leafed bascule bridge with vehical traffic. In the same state Louisiana southern part are numerous of identical vertical lift bridges crossing the Bayous such as the state route 344 lift bridge crossing the Teche bayou at Loreauville,http://www.flickr.com/photos/94273918@N06/9730292513/ Breaux Bridge, http://www.flickr.com/photos/94273918@N06/8725570765/Bourg, http://www.flickr.com/photos/94273918@N06/8751295410/and Petite Calillon bayou lift bridge in Terrebonne Parish are the prime examples of the lift bridges in the southern state of Louisiana and many more.

Canada Duplicate Movable bridges Edit Text

Canada has, mostly in Ontario, numerous vertical lift bridges and rolling lift bridges crossing the Welland canal. In Welland Ontario, there ares a few identical lift spans which carry vehicles and some railroad bridges. The Kings Highway lift bridge in Rural (Allanburg) and No#11 bridge both has the same tower and span structures along with counterweights.
