13.00 linear feet
Begun in 1867 and completed in 1874, the Eads Bridge was named after its designer, James Buchanan Eads. It was the first bridge to span the Mississippi at St. Louis, the first bridge to make significant of steel, and one of the first bridges in the U.S. to make use of pneumatic caissons (the caissons sunk for the bridge are still among the deepest ever). It was also the first bridge to be built entirely using cantilever construction methods, avoiding the need for falsework, and the first bridge designed so that any part could be removed for repair or replacement. The bridge is now a National Historic Landmark.

book A history of the St. Louis bridge : containing a full account of every step in its construction and erection, and including the theory of the ribbed arch and the tests of materials : illustrated by numerous wood-cuts and fifty full-page lithographs and artotypes / by C. M. Woodward (1881) http://catalog.wustl.edu:80/record=b1901130~S2
In this inventory, all of the Eads Bridge drawings, from both American Bridge Company and Terminal Railroad Association, have been brought together in order to facilitate their use and are arranged numerically by the Terminal Railroad number. A separate inventory containing only the 93 American Bridge drawings is available.
Each of the drawings is individually numbered and described. No attempt has been made to organize the drawings by date, portion of the bridge covered, etc. The following information is given for each drawing:
Drawing number: Unique number, assigned by W.U. for identification purposes; will have the form "TR-#/AB-#"
Title of drawing: Description of drawing by the original architects; copied verbatim from the drawing.
Scale of drawing
Date of drawing
Signature which appears on the drawing: Usually the name of either James Eads or Walter Katte, resident engineer for the Keystone Bridge Company, which fabricated and erected the bridge's superstructure.
Microfilming note: If the word "Microfilmed" appears, then a microfilm copy exists of this drawing. All the microfilmed drawings are available on one reel of film housed in the University Archives.
Dimensions of drawing
If any of these elements is missing from the description, it means that the information does not appear on the drawing.
Physical Access Requirements
Because of their age and physical condition, the original drawings require advanced notice when visiting the Archives. When possible high resolution digital copies will be shown to researchers instead of original drawings.
Method of Acquisition
The 93 drawings from the American Bridge Company were placed on permanent loan to Washington University and the Museum of Transportation in 1978 by the U.S. Steel Corporation, American Bridge Division. The company is now known as the American Bridge Company, and this company continues to hold ownership of the drawings.
The 570 drawings from the Terminal Railroad Association were placed on deposit at Washington University in 1974 by the Terminal Railroad Association. A deed of gift turning over these drawings to Washington University was executed in June 1997.
Drawing inventory completed by Catherine Forslund, graduate student worker, in 1997. Finding aid written and converted to DACS format by University Archives staff.
