Wikipedia:WikiProject U.S. Roads/Oklahoma/History

The ODOT web site has a section that lists memorial highways and bridges on Oklahoma highways. While this is of marginal importance to the articles, each page also contains a complete history (changelog) of each route that has a memorial name or bridge on it. This means the coverage is patchy, but a complete history section can be gleaned from it with the help of the state map archive.

The site is at.
