As this photograph from late summer 1937 clearly illustrates, all three spans of the Butler Bridge remained intact until the end. The approach span at this end is original to the structure. The far abutment is all that remains intact at this location though the abutment footings are visible in the river bed. The abutment at this end is now just a pile of discarded stone.

To my knowledge there has never been any indication that the original work on the bridge was sub-standard. No mention of this appears in any record I have researched and such sub-standard workmanship would have caused problems with the structure much earlier than 1937. The bridge was repaired by the Bower Bridge company in 1904.
Second: The 1937 flood did NOT cause one of the spans to be destroyed. The bridge was used (though the roof and siding were removed prior to 1934) until the new bridge was completed in September or October, 1937.
Third: AND AGAIN. The bridge at Butler was NEVER the longest covered bridge in the world. It was never the longest in the United States. It WAS the longest ever built in Kentucky.

Unfortunately Walter, I have found way too many of these historical markers with incorrect information.
This one seems to be chock full of it!
