Bascule bridge is a movable draw bridge.  These can be one leaf or two leafs.    In a single leaf bascule bridge,  there is a single movable span that bridges the entire river.  In a double leaf bascule, there are two movable spans that meet in the midline

Fixed trunnion.  The bridge rotates about a fixed axis.

Truss Bridge is one whose load bearing superstructure is composed of A truss–structure of connected elements usually forming triangular units

Warren Truss Bridge was patented in 1848 by James Warren and Willoughby Theobald Mongani.   Its longitudinal members are joined only by angled cross members forming alternatively inverted equilateral triangle shaped spaces along its length

A Pratt Pony Truss. The truss is above the road bed but not connected.

Through truss.  Truss members are above and below the roadbed

Deck truss.  The roadway is atop the truss.

The Columbus Drive Bridge  ( 300 east and 400 north ) crosses the main branch of the Chicago River 3/10 a mile west of the river mouth.   Currently it is the world’s second largest bascule bridge.   It was built in 1982.   Cost of construction was $33 million. The largest span is 269 feet.  Total length  is 389 feet.   Deck width is 89.8 feet.

It is a single piece box truss similar to the Loomis Street Bridge.  There are 8 trusses 4 in each leaf.    During its short history, there have been two incidents involving the bridge:  1 April, 15, 1983 cracks were found in three of the gears;  May, 1984  bridge failed to open due to binding of the center bolt.

This is also known as the William Fahey Bridge  (a police officer killed in the line of duty).  It is a metal, movable double leaf bascule (fixed trunnion) and approach spans: metal stringer (multi beam) fixed

     The Lake Shore Drive Bridge crosses the main channel of the Chicago River inside the locks separating Lake Michigan and the river.  The current bridge is the only bridge at this site.   Lake Shore Drive was also known as Erickson Drive and Field Boulevard.  It was named Lake Shore Drive in 1946.

      Planning of this structure began in 1926.  Construction started in 1931.  Funding ran out in 1932.    The WPA provided funds in 1935.  Project was completed in 1937.   Cost of The project was $11 million.   The bridge was dedicated by President Franklin Roosevelt in October, 1937.  At completion, it was the largest and heaviest double leaf bascule bridge.

     In addition to the main bridge, there was a single leaf bascule bridge traversing the Ogden Slip.  This was a man made channel paralleling the Chicago River (North of the river).  This was built by the Chicago Canal and Dock Company.  This was used as a harbor and warehouse space.  One of the warehouses on the slip was the Pugh Terminal.

     The main bridge was a rivet-connected-Pratt Deck Truss,movable double bascule (fixed trunion) and approach spans: metal stronger (multi beam), fixed. This was a two level bridge.  The lower level was originally planned for a railroad.  There was one main span and three approach spans.  The main span length is 264 feet.  The structure length is 356 feet.  Overall roadway width is 108 feet.   Each bridge leaf weighs 6,420 tons.  The bridge was dedicated as the Franklin Delano Memorial Bridge in 1982.

There are 4 impressive lock tender houses.

The bridge over the Ogden Slip had similar appearance in its deck trusses and bridge tender houses as the main bridge.

Bridge builders include: Al. Johnson Construction Company, M.E White Company, Warner Construction Company,  Paschen Brothers, Fitzsimmons– Connel Dredge and Dock Company, Great Lakes Dredge Company, Ketler–Elliot Company, Mackie–Thompson–Tamm, Bethlehem Steel Company, W.E. O’Neill Construction Company, American Bridge Company, Oscar Daniels Company, Pierce Electric Company, Thomas McQueen Company.  Joseph Srauss was a consulting engineer.

The upper level of the bridge originally had a pedestrian walk.  It had  unique railings.   The walk and rails were lost during a bridge widening project.  Originally, there was not a pedestrian walk on the lower level.  This was added on the east side.   It is a sidewalk that also carries the lakefront trail.  It is extremely busy.  One proposal was to build a new walkway adjacent to the bridge.  Another proposal was to widen the existing sidewalk.

The bridge under went an extensive rebuilding project in 1987. The original southern s shaped curve was straightened.  The lower deck was converted for auto use.  It serves as a feeder for Randolph Street, Wacker Drive, Illinois Street and Grand Avenue.  The Ogden Slip bascule bridge was removed and converted to a fixed structure.

     Along the north bank of the main branch of the Chicago River at  325 North LaSalle Street is an impressive multi-story structure known as the Reid Murdoch Building.  It was designed by George Nimmons.  It was built in 1914 for a whole sale grocer supplier known as Reid, Murdoch and Company.  This business was one the nation’s largest of this type.

     The building was used for corporate offices and warehouse storage. Some of the floors were dedicated to manufacturing and processing–cheeses, coffee, catsup, fish, bread and pickles. There was even a large humidor where cigars were manufactured.  The building has an ideal location with the Chicago River to the south and railroad access to the north.

     The building was a 7 story  brick structure.  There were terra cotta embellishments. The building skeleton was steel and concrete.  There is a central multi-story tower. At one time, this housed a water tower for the building sprinkler system.  Originally, the building was symmetric about the tower.  However, in 1926, one bay of windows on the west side was removed when LaSalle Street was widened.

     For a brief time, the building was used as a makeshift hospital during the Eastland disaster in July, 1915.

     Reid, Murdoch operated in the building until 1945.  The company was acquired by Sprague–Warner–Kenny Corporation.  This eventually became part of Consolidated Grocers.

     In the 1950’s, the city of Chicago acquired the building. It housed traffic courts, states attorney offices and other municipal departments.  The city occupied the building until 1998.

  The building was then acquired by Friedman Properties.  They conducted an extensive  rehab project.  The building is operated as rental property. 

     The building was designated as a Chicago Landmark.  It was listed on the National Register of Historic Places.
