INDUSTRIAL PORTS AND HARBORS

 

Industrial ports are harbors where ships dock from city to city, transporting supplies (such as oil or salt) -- drawbridges are able to open to allow them to pass through from the harbor to narrower channel areas. Ports harbors in locations like Cleveland, Chicago, Detroit, Milwaukee, Buffalo, New Orleans have drawbridges of all types that are operated by bridge tenders. These tenders open and close them to allow ships to pass under, and traffic to pass over the rivers. Industrial ports are like other ports, but are used by ore docks for ships that carry industrial supplies and materials. When business of industry is good, these drawbridges ( bascule, lift, or swing bridges) remain in operation. When industry decreases, these bridges end up abandoned, out of service or demolished. Cleveland in it's history had more movable bridges than any other city, except for Chicago. In the early day of the 1800's, swing bridges were made from wood.

CLEVELAND

There were once several swing bridges across the Cuyahoga river, industrial Cleveland's connection to Lake Erie, which have been replaced by bascule and lift bridges. The Columbus Road bridge, for example, was a double swing bridge until in the 1930's, when a vertical lift bridge was constructedhttp://www.flickr.com/photos/94273918@N06/8646373360/ (the new bridge was designed with drive machinery on the lift span -- a span drive bridge.). The Wheeling and Lake Erie Railroad (also known as the "Iron Curtian railroad") operated a swing bridge and a Willow Avenue swing span, both of which were replaced by lift bridges. http://www.flickr.com/photos/94273918@N06/8602313141/The http://www.flickr.com/photos/94273918@N06/8645273255/only swing bridge remaining is the Center Street swing bridge, constructed by the King Bridge Company as a rim bearing bobtail type swing bridge. http://www.flickr.com/photos/94273918@N06/8646326614/This bridge is still in operation.

Today Cleveland has only fifteen movable bridges: ten vertical lift bridges (five for vehical traffic, and five for railroad traffic), four railroad bascule bridges (Two are out of service,and 2 still in service) and a swing bridge. Of these, only eleven of them are in operation. The Cleveland movable bridges are:

- near the ISG steel mill, abandoned

CHICAGO

Chicago has over 52 movable bridges, more than any other city, over the Chicago river (North and South branches) Calumet river, and Sanitary or Drainage canal in the state of Illiniois. The first trunnion bascule bridge was a Cortland street bridge, a Chicago type bascule design. http://www.flickr.com/photos/94273918@N06/8666258432/This bridge remains fixed in the closed position because ships no longer pass for the bridge tenders to operate the double leaf lift span. It is still used by vehicles. Back in the early Century a Halstead lift bridge was once constructed, and later was replaced with a bascule bridge.

The Cermark road bridge is one of few Scherzer type rolling lift bridge with a double section, operated by the city of Chicago. http://www.flickr.com/photos/94273918@N06/9678551131/The Orleans street bridge is still used by the city of Chicago. http://www.flickr.com/photos/94273918@N06/8666258122/Other bridges still in use include Jackson Boulevard bridge, http://www.flickr.com/photos/94273918@N06/8617557456/Washington Boulevard bridge,http://www.flickr.com/photos/94273918@N06/8648367239/ Michigan Avenue bridge http://www.flickr.com/photos/94273918@N06/8602847649/,Wells street,http://www.flickr.com/photos/94273918@N06/8666258066/ Canal street,http://www.flickr.com/photos/94273918@N06/9100908507/ Grand Avenue, http://www.flickr.com/photos/94273918@N06/9681964222/Ashland Avenue,http://www.flickr.com/photos/94273918@N06/9678654841/ East and West Division street http://www.flickr.com/photos/94273918@N06/8666257718/bridges,.http://www.flickr.com/photos/94273918@N06/8666257678/Ohio street bridge,http://www.flickr.com/photos/94273918@N06/9682074796/Monroe street bridge,http://www.flickr.com/photos/94273918@N06/9681964046/Lake street bridge,http://www.flickr.com/photos/94273918@N06/9682112914/Outer Drive bridge,http://www.flickr.com/photos/94273918@N06/8648367343/ Madison street,http://www.flickr.com/photos/94273918@N06/8665158027/ Randolph street.http://www.flickr.com/photos/94273918@N06/8750613319/ Columbus Drive,http://www.flickr.com/photos/94273918@N06/9682172338/ Congress Parkway bridge,http://www.flickr.com/photos/94273918@N06/9682221884/ Lake Shore Drive bridgehttp://www.flickr.com/photos/94273918@N06/8648367343/, Wabash Avenue,http://www.flickr.com/photos/94273918@N06/9681892418/State street, http://www.flickr.com/photos/94273918@N06/9100908401/Dearborn street,http://www.flickr.com/photos/94273918@N06/8649471364/ Clark street,http://www.flickr.com/photos/94273918@N06/9678654785/ Kinzie street ,http://www.flickr.com/photos/94273918@N06/8648367699/ North and South Halstead street bridgeshttp://www.flickr.com/photos/94273918@N06/8666258168/http://www.flickr.com/photos/94273918@N06/9103137128/.

All trunnion bascule bridges crossing the Chicago river, North and South branches are road bridges. Operated by the Union Pacific railroad, one spans the North branch Chicago river, a 3 track 180 foot Strauss heel trunnion type bascule bridge which is still in service, but is in the closed position. http://www.flickr.com/photos/94273918@N06/8589811648/Another bridge, abandoned, is a double track 170 foot Strauss Overhead Counterweight bascule bridge in the open positionhttp://www.flickr.com/photos/94273918@N06/8589916244/.

The four railroad Scherzer type rolling lift bridges also inoperatable side by side left and right in closed shut, http://www.flickr.com/photos/94273918@N06/9042746671/and a couple of swing bridges for rail traffic. Theyr'e also double deck bridges that carries both upper deck highway and lower deck railroad. Today are still the city of movable drawbridges that holds a large record in the windy city. People go to and from work crossing each bridge and exploring them, Chicago is a famous place for drawbridges, for the past bridge building inventors their offices are in downtown Chicago.



DETROIT

Detroit has 9 drawbridges then has 8 and a swing bridge crossing the Rouge river in the state of Michigan.

It is very difficult to get to explore these bridges except by boat. But they have some historic imformation about them in the library in Detroit, and on the computer. All are still operatable.



MILWAUKEE

Milwaukee's drawbridges are a similar to Chicago's drawbridges. They have 3 waterways, Milwaukee river, Kinnickinnic river, and Menominee river in the state of Wisconsin. Milwaukee has all together 30 drawbridges, 6 crossing the Kinnickinnic river, 8 crossing the Menominee river, and 16 crossing the Milwaukee river.
