Searching for information for Jerald Dyer:

Back in the late 20's maybe early 30's, I had family that actually operated the toll road or bridge over the South Canadian River leading into Bridgeport. I even have a picture of them standing in front of the store which was at the entrance, I believe. That same picture is in the museum there at Geary as well, because my dad donated it several years ago. What I would like is to find all the info on that toll road that there is. The columns are still standing, just east of the train bridge. I am fascinated by the history of the place where I was raised, and would love anything you can find more me or tell me where to look myself.
Thanks for any help you can offer. I appreciate it very much.
