The Historic Bridges Of Oklahoma



  To travel the major highways and country roads of the Sooner State is to encounter a variety of bridge types that together made possible a dramatic improvement in transportation between the 1890s and 1930s.  In the midst of this time period, Oklahoma became a state (1907) and began expanding its road system.  This effort, stretching over the years and involving both local and state governments, occurred at the same time that American bridge builders were perfecting an array of standardized bridges for use on the highways.  Thus, Oklahoma's formative years meshed with this stage of industrial and technical progress to furnish the state with a significant cross section of the dominant bridge types, principally steel trusses, which were then serving to modernize and link together a nationwide system of roads.  Although the forces of time, nature, and progress have taken a toll, many of these bridges remain to convey the impact of these changes.  The ones chosen as significant represent the most notable and characteristic features of this development in the history of Oklahoma transportation.  The Oklahoma Historic Highway Bridge Project identified 171 bridges as candidates eligible for listing on the National Register of Historic Places.
