From reviewing historic aerials, I stand corrected RE: my previous comment. The abandoned bridge here served the Jefferson Highway, and the bridge was built BEFORE highway 71 was straightened in the late 1960s. Historic aerials shows both bridges extant in 1955.

Curious if this bridge was really built in 1931 or if the abandoned bridge is a 1931 product and this is of a later date.
