2021 Update for Truss and Arch Bridges
Oklahoma Historic Bridge Update for Metal Truss, Masonry Arch, and Concrete Arch Bridges Constructed through 1980 (January 2021)
In 2021, ODOT completed an update and evaluation of all remaining truss and arch bridges in Oklahoma. Twenty-one of the 348 remaining bridges evaluated were previously listed on the National Register of Historic Places (NRHP). The study found 164 bridges eligible for the NRHP. Of those 164 bridges, eleven were found eligible under Criterion A only, 99 under Criterion C only, and 54 under both Criteria A and C. The remaining 163 bridges were determined to be ineligible for the NRHP.
The report provides a historic context and a list of all 348 bridges and their National Register evaluation.
