Red River Moncla Bridge
Posted October 17, 2017, by Jeff Dubea (jeffdubea [at] yahoo [dot] com)

I went over the Moncla Bridge many times. Just downriver, there are still concrete pilings visible from an even older bridge. The older bridge was built in the 1920s or 30s (possibly WPA, because I was told my grandfather worked on it) and collapsed during high water. There is still a road bed on the east side of the river going to the bank. The man who owns the property tells the story and heard that a car went off of the bridge when it fell. I'd like to know more about this, if anyone has information.
