 The Dearborn Street Bridge (50 West; 307 North) runs North and South across the main channel of the Chicago River .85 mile from the river mouth.  It  has the distinction of being one of the youngest Chicago bridges.  It opened in October, 1963.   It was two years behind schedule for multiple reasons: 1) Constructions snags; 2) disagreements between the city and the contractors; 3) national steel workers strike; 4) Construction of adjacent Marina City.  It was rehabbed in 2006.

  The bridge description is a metal rivet-connected Pratt Railing Height Truss, movable; double leaf bascule (fixed trunnion; approach spans: metal stringer (multibeam) fixed.   The bridge is steel.  A unique feature is the presence of only one bridge keeper house.

There is one main span and 4 approach spans.  The main span length is 235 feet.  The structure length is 341 feet.  Roadway width is 56 feet.

Contractors were as follows:

Builder/Contractor   Overland Construction Company of Chicago  (Bid $2,685,134)

Engineer/ Design City of Chicago

Substructure Contractor  States Improvement Company  ( Bid $1,162,050)

Electric Contractor  Garden City Engineering (Bid  $630,992)

     This area was the site of multiple prior bridges.  The first bridge was built in 1834.   It was a movable bridge.  It was 300 feet long and 16 feet wide.  It was a yellow frame wood hand operated bascule design.  It was designed and constructed by Nelson Norton.  The city council voted to remove this bridge on July 8, 1839.  Irate citizens took matters into their and demolished the bridge.   A replacement bridge did not come for years.  In the interim, there was a ferry service at this site.

       The second bridge at this site was built in 1888.   It was an iron, hand operated  swing bridge.  The construction project involved floating Wells Street Bridge  superstructure  (built in 1872)  to Dearborn Street on scows.  This was then mounted on new center piers and foundations.   Bridge was designed by Fox and Howard.   They were also the  superstructure contractor.  Substructure contractor was FitzSimons and Connell.  Cost was $22,800.     At some point in time, the bridge was converted to steam power.  In 1897, it was converted from steam to electric.  In 1901, Chicago Union Traction replanked  the entire roadway.  There was a history of multiple collisions involving the bridge.   The bridge was removed In 1907.

 In 1907, a Scherzer rolling lift bascule bridge was built at this site.   The bridge was constructed by the Sanitary District.  Superstructure Contractor was George Jackson, Inc.   Substructure Contractor was Great paLaces Dredge and Dock Company.  Cost was $316,067.72.   This bridge was removed in 1959

      The current Clark Street Bridge ( 200 West; 307 North) runs North and South across the main channel of the Chicago River 1.2 miles west of the river mouth.  It is the eighth bridge at this site.  It was completed on July 10, 1929.    It was described as a metal river-connected Pratt Pony Truss, movable double leaf bascule (fixed trunnion) and approach spans , metal stringer (multibeam); fixed.   It consists of one main span and 3 approach spans.    The main span length is 245.4 feet. The structure length is 346 feet.  The deck width is 38 feet. The bridge deck is open grating.  There are four lanes of traffic.  There are two sidewalks.  There are two beaux arts style bridge tender houseses.  They have mansard tin roofs. The bridge was rehabbed in 1985.

The following is a list of contractors:

Builder/Contractor Ketler–Elliot Company of Chicago.  Substructure Contractor FitzSimons and Connell Dredge and Dock Company.   Electric Contractor Norwood and Noonan Company.

The bridge was designed by Loran Gayton and city bridge engineer Paul Shioler.

Bridge cost was $1,529.492.77

      The discussions about building a bridge over the Chicago River were quite acrimonious lifting North and South sides.  Finally, a bridge was built in July, 1840.     It was a hand operated pontoon float swing bridge. It was constructed by William Ogden.  Cost was $3,000.00  It was destroyed in the flood  of 1849.

     A second more substantial pontoon float swing operated was constructed in July 3, 1849.  Like its predecessor, it was also hand operated. The bridge was 10 to 12 feet above the water.  The bridge was designed and come by John Censon.  Total cost was $2800.   The city contributed $1500 and the adjacent property holders contributed the balance.  In 1853, the bridge was destroyed in a collision with steamer London.  The destroyed bridge was repaired and relocated to Polk Street.
       The third bridge at Clark Street was built by July 4, 1854.    It was designed and built by Derastus Harper (City superintendent of Public works).  It was a pivot bridge with sidewalks and a double carriageway for north and southbound traffic.  It was 330 feet long and 30 feet wide.    It incorporated protection piers to protect the open bridge.  Throughout its history, it had structural problems.    On July 28, 1858 It split in two pieces. 

    The fourth bridge at this location was a Howe truss wood operated swing bridge.  It was designed and built by Chapin and Company in 1858. Construction cost was $14,200.

     It was one of the busiest bridges across the Chicago River.    It had to be replanked in 1859.  In January 1866, the City Superintendent reported that the bridge was rotten and unsafe for traffic.  It was removed on April 6, 1866. 

     The fifth bridge at this site opened on June 9, 1866.  It was the first wood and iron hand operated bridge in Chicago.  It incorporated an improved Howe Truss and a new turntable patented James K. Thompson.  

     It was 180 feet long and 32 feet wide.  It was designed by the Board of Public Works and James Thompson.  It was constructed by Thomas Makin.  Construction costs were $13,800.00.  The bridge was destroyed in the Chicago Fire of October, 1871.

     The sixth bridge at this location opened on January 9, 1872.  It was a Howe truss swing wood and iron bridge.  It was hand operated.  It was designed and constructed by Fox and Howard.  Construction cost was $32,000.00.  

     In 1889, the bridge was moved Webster Bridge.

     The seventh Clark Street Bridge opened in 1889.  This was a joint project with the city of Chicago and the North Chicago Street Railroad.  The railroad paid for the superstructure and ongoing maintenance.  The city paid for the substructure.  This was a steel Pratt truss steam powered swing bridge.  There was a street car and traffic land in each direction. 

    The bridge was designed by the North Chicago Street Railroad.  Superstructure Contractor was Variety Iron Works.  Substructure Contractor was FitzSimons and Connell.  Cost was $186,562.

     This was a busy bridge.  In 1897, the bridge was converted from steam to electric power.  In 1907, the roadway was repaved. In 1929, the bridge was severely damaged in a collision with the sand barge Sandmaster.   It was subsequently demolished.

       The current bridge (100West: 307 North) spans the main  Chicago River North to South 1 mile west of the river mouth.   It opened on December 20, 1928.  Its official description is metal rivet-connected Pratt Pony Truss double leaf bascule (fixed trunnion); approach spans: metal stringer (multibeam),fixed. The largest spam is 242 feet.  Total length is 347 feet.  Deck width is 56.1 feet. 1 main span and 3 approach spans

     It is the first bridge  at this location.  It is one of the most ornamental bridges.    There are 4 Bridge Tender Houses.  2 are really not needed.  These houses have Baroque style ornamentation.

 

     The bridge designers were city engineers Donald Becker, Thomas Pihlfeldt, and Clarence Rowe.   Superstructure  Contractor was Stroebel Steel Construction Company; Substructure Contractor was Central Dredging Company.  Kelly Atkinson Construction Company was contractor for all 4 bridge tender houses.  Electrician was Norwood Noonan.

Total cost was $1.8 million.

     A tunnel was the first connection  between North and South La Salle Street.  Construction began on November 3, 1869.   It was designed by William Bryson.  Construction was done by Robert Moss.  The project was completed on July 4, 1871.  Cost was $566,000.  Length was two thousand feet.   Originally, the tunnel was designed for both pedestrians and horses drawn vehicles

    Because the tunnel was dark, it was underused.  It was more valuable to street car companies.

     When the flow in the Chicago River was reversed, the depth of the river was increased.   This necessitated a deepening of the tunnel.   This project was completed on June 22, 1912.  Use of the tunnel decreased.  It was permanently closed in November, 1939.

    

The bridge was dedicated in 1999 as the Marshal Sulloway Bridge (former commissioner of public works)

      The current Wells Street Bridge ( 200 West; 309 North) is the eighth bridge at this site. It crosses the main branch of the Chicago River 1.4 miles west of river mouth.  It is one of the four double deck bridges over the Chicago River.  

     It Is a metal rivet-connected  Warren through Truss movable; double leaf bascule (fixed trunnion) and approach spans :  metal stringer (multibeam ); fixed.  The upper decks carries two tracks of the CTA elevated line. On the lower deck, there are cantilevered side walks.  There are two granite faced octagonal bridge tender houses.

     There is one main span and four approach spans.  Main span measures 268 feet.  Structure length measures 345.2 feet.  Roadway width measures 38 feet.

     To minimize railroad traffic disruption, the bridge was constructed in the open position.  I have found at least two dates for the bridge opening:  December 4, 1921 or February 11, 1922.

     In 1935, there was a collision between a ship and the bridge.  The east side sidewalk was torn away.  There was also damage to the superstructure.  In 1936, there were two bridge malfunctions in a ten day period.  In 1936, new creosoted  block deck pavement was installed. Four main columns of the bridge approaches were reinforced with horizontal trusses.  In 1956, the old bridge deck was removed and replaced with open grid steel roadway.  The bridge was closed to traffic beginning in November, 2012 for a complete bridge rehabbed.

     The following were bridge contractors:

Designer:  Bureau of Engineering Chicago Department of Public Works.

Substructure Contractor:  Fits Simons  and Connell Company

Superstructure Contractor:  Ketler Elliot Company.

Steel Fabricator:  Fort Pitt Bridge Company

Construction Cost  $1,341, 925.

     The first bridge at Wells Street opened in 1841.  It was a wood hand operated pontoon – float swing bridge. There were wood approaches at each end. It was designed and built by John Van Osdel.  Cost was $3500.  It was removed in 1847.

     The second bridge at Wells Street opened in July, 1847.  Like its predecessor it was a pontoon swing design.  Its   floats were made from boiler iron.  Neither the bridge designer not the builder are known.   Construction cost was $3000.  It was destroyed by a flood on March 12, 1849.

     The third Wells Street Bridge opened in September, 1849.  It was a new pontoon-float swing design operated with a turn table.  It was hand operated.  It incorporated salvaged floats from the second bridge.  Neither the designer nor the builder are known.  Cost was $3200.  The bridge was removed in 1856.

     The fourth Wells Street Bridge opened in 1856.  It was a swing wood hand operated type bridge.  It was 190 feet in length and had 3 arch trusses.It was designed and constructed by Derastus Harper City superintendent of public works.  Construction cost was $20,000.

     In 1861, the bridge was strengthened with cables to relieve strain.  The bridge was eventually removed in August, 1862.

     The fifth bridge at this site opened in 1862.  It was a wood swing pivot hand operated bridge.  This bridge used the foundation and turntable of its predecessor.  It was designed and constructed by Fox and Howard.  Cost was $8000.00. It was destroyed in the Chicago Fire of October 8–10th, 1871.

     The sixth Wells Street Bridge opened in  August, 1872  It was an all iron swing hand operated bridge  It was 190 feet in length.  It required an all new substructure .  It was designed and constructed by Fox and Howard.  Its cost was $49,002.  After 16 years of service, the bridge was relocated on March 26, 1888 to Dearborn Street.

     The 7th Wells Street Bridge opened on August 24, 1888.  It was an all steel swing bridge.  Originally it was powered by steam.  This was later converted to electric power.  It was 220 feet long.  Part of the financing was provided by North Chicago Street Railroad Company  ($59,000 + $4,690 operating costs).  City of Chicago paid for the substructure.  Total construction costs were $112,692.

     Bridge designer and superstructure contractor was Keystone Bridge Company.  Substructure contractor was FitzSimons and Connell.

     In 1890, Department of Public Works made repairs to the center pier and North approach.  In July 5, 1896, the bridge was closed so that the contractor Shailer and Schniglau could add a top deck to carry the trains of the Northwestern Elevated Railroad Company.  A new set rollers was added to the bridge turntable.  Seven Center panels were removed from all three bridge trusses and were replaced with heavier steel.  Bridge reopened in September 20 of the same year.The

     The bridge closed on December 3, 1921 and then was removed.

     This is a railroad bridge over the north branch of the Chicago River.  It is located between the Kinzie Street traffic bridge and the Lake Street Bridge.  It was built in 1908.  It is one of the few single leaf movable bascule bridge with the counterweight above ground and independently moving.  The bascule superstructure was a design by Joseph Strauss.  The steel superstructure was fabricated by Toledo Massillon Bridge Company of Toledo.   The substructure was designed by William Finley.   The largest span is 170 feet.  Total length is 196 feet.  There is one main span and one approach span.  The bridge was built for the Chicago and Northwestern Railroad.  At the time of construction, this was longest and heaviest bridge of this type.  It carried passengers and freight to the Wells Street station.  Eventually, it carried only freight.  Its last customer was the Chicago Sun Times.  In 1995, CNW was taken over by the Union Pacific Railroad.

 

 

Although the line was abandoned in 2001, the bridge is operated once a year.  It is stated that the bridge is in good mechanical order.

The bridge has been known by multiple names.  These include:  Kinzie Street Railroad Bridge (ironic because the bridge is actually located at Carroll Street), North Branch  Railroad Bridge, CNW Wells Street Bridge (after the CNW Station).

There have been many bridges at this site.  There was a railroad bridge from 1852 here.  One of the first all steel bridges was built at this site in 1879.   This bridge was replaced with lattice through truss swing bridge in 1898.

   There have been six bridges at the Kinzie Street site. The location is historic because: it is the location of the first Chicago bridge (1832); the site of a river fire (1899);site of a flood that shut down the city center for one week (1992).   The current Kinzie Street Bridge (423 west; 400 North) crosses the North Branch Chicago River 1.8 miles from river mouth.  It crosses east to west.   Its technical description is Metal Riveted-connected Pratt through Truss, movable single leaf bascule (Fixed trunnion).  Approach spans metal stringer, fixed.   This bridge is the only remaining single leaf bascule from the first generation through truss.  It opened on May 10, 1909.

     In 1910, danger signals were installed on the west approach; the deck was paved. In 1931, the east bridge house was elevated above the sidewalk and was rebuilt.  In 1939, the upper two stories of the State Street Bridge house were moved to the sw corner of the bridge. In November, 1998,Kinsey Street was closed and the bridge structure was elevated 5 feet.  Bridge was converted from movable to fixed.  The bridge was rehabbed extein 1999.
