History of Oklahoma Highways

Today seems to have evolved into an Oklahoma History theme.  Fine, let it go in that direction then.  Here is another one of Wes Kinsler’s sites that I have used often. This one is about the history of Oklahoma Highways.  It’s good for armchair traveling, either down the highway or backwards into time.

Oklahoma Bridges

A photographic history of bridges throughout Oklahoma, and some discussions and diagrams of the various kinds of trusses. Especially useful for students working on a balsa-wood bridge for Engineering Day!  The pages “Bridge Design” and “Oklahoma Bridge Types” would be excellent required reading for these students.
