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.


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were once several swing bridges across the Cuyahoga river, industrial Cleveland's connection to Lake Erie, which have been replaced by bascule and lift bridges.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 constructed (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. swing bridge remaining is the Center Street swing bridge, constructed by the King Bridge Company as a rim bearing bobtail type swing bridge. 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

- a rolling lift bridge constructed in 1907 by William Scherzer, a record making project in the flats in its time, abandoned

- a bascule bridge for the Wheeling & Lake Erie railroad constructed by Joseph Strauss in 1905 next to the West 3rd street lift bridge (West 3rd still in operation). This bridge has been removed

- Erie railroad bascule bridge, demolished in 1985 next to the twin bascule bridges.

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. 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.
