I was in charge of the conatuctionof this bridge in 1953. The trusses used in this bridge were salvaged from the brg over the auxvasse river of rte 40, Callaway co. They were dismantled in sections, stored at the maint bldg in Auxville and then transported to the brg site. Some modifications were made especially on the bearing plates. Would be glad to discuss this further with you.
