IDOT Historic Bridges Survey

In November 1990, with the signing of a Memorandum of Understanding (MOU), compliance procedures were established between the IDOT, IHPA and FHWA. The MOU required the establishment of a list of structures with historic significance to be called the Historic Bridge Survey (HBS). Some 350 bridges were included in the initial HBS, and these structures were to be divided then into “primary” and “secondary” examples of the various bridge types.
