Reading through some correspondence with the Association this morning, I was presented with this web link: www.odotculturalresources.info. It takes you to the Oklahoma Department of Transportation’s Cultural Resources Program website.
Of particular interest to Oklahoma Route 66 enthusiasts is the section on historic bridges and the surveys that ODOT has performed on historic bridges in Oklahoma. The most recent inventory is the Oklahoma Historic Bridge Survey: Reevaluation of Spans of Time (May 2007). There is a specific list of historic bridges located on Route 66. There is also a link to county-by-county maps with the historic bridge locations marked.
Another portion of the bridge section has historic bridge narratives. These are the Historic American Engineering Record (HAER) standard documents covering the bridge’s history. I don’t see the narrative for the recently replaced Verdigris bridge though…
Another section worth exploring is the Links section. Here you will find links to Federal regulations related to historic preservation. This is interesting from the standpoint of making yourself knowledgable about the “rules” that federal/state agencies have to follow when dealing with historic properties.
