FYI. I checked the MoDOT Vendor Plans Room and can confirm there is a Spring River Bridge replacement contract being bid on, however there does not appear to be any contract for the RR bridge at this time. If it is up for replacement, the contract was either was let some time ago, or has yet to be posted for bidding.
I too thought that this was the bridge scheduled to be removed this summer, but MODOT map and Carthage City says it is the 1953 Spring River bridge. Could you e-mail me with any details. I also have a map of Carthage circa 1929 that shows two bridges over Spring River and a small tributary. The main bridge on the park side was removed (when?), but do you know about the second bridge that carried original 66 traffic onto River Street? Also, when the 1934 viaduct was built, where did the road go heading east at that time? Was it to the "V" highway which was the first alternate of 66? I am trying to fix exact dates for these bridges. Thanks.
