Thanks for the input. I once assumed that these bridges were quite common having seen several in Kansas. It has only been in recent years that I have realized their importance.
Its possible that today, states like Illinois and Kansas have more straight chord concrete girders than Michigan (where many have been demolished). If you've looked at my listings on HistoricBridges.org, I've photographed all known concrete girders. However, the same cannot be said for Illinois and Kansas where neither Bridgehunter or HistoricBridges.org have full coverage of that bridge type (often NBI-classed as concrete slab)... so I expect that there are more of these bridges out there in these states than currently known.
Ohio has a number of concrete thru girders (quite a few with shallow curves too). That pretty much completes the list of states with substantial populations of thru girders.
These through girder bridges are always a nice find. On a national scale, they seem to be surprisingly uncommon.
Michigan of course is famous for its curved concrete through girder bridges. Michigan also has many straight concrete through girder bridges, but Illinois, Kansas, and a few other states have their share as well. That being said, I don't know any region of the country in which concrete through girder bridges are overly abundant.
These concrete through girder bridges should not be confused with concrete tee beam bridges or any concrete slabs that just happen to have nice concrete railings. The NBI occasionally categorizes these bridges incorrectly. WWI and 1920s era concrete through girders are much less common than beam and slab bridges.
Have to say the drive to this one is a little bit prettier than the bridge itself, still a very neat 95 year old stone pony
