Bridge near Hannibal, MO
Posted October 2, 2012, by Barb Valley (barb [at] mahvelousmailboxes [dot] com)

About 5 years ago I was leaving Hannibal, MO on my way North back to Wisconsin. I do not remember what road I was on- I just remember turning onto a rather large bridge, going up, over a large river (I assume the Mississippi) and suddenly I was on the most terrifying, dilapidated busy bridge. I remember seeing old wood handrails, 1 narrow lane each way, no shoulder- nothing to save you should you not be paying attention. Well- I am going to be in Missouri again, and would love to check out that bridge. Does anyone know what one I could be talking about? What road is it on? Any help is appreciated. Thanks in advance.
