This event occurred after the long drought in the early 1950s: https://www.newspapers.com/image/638364744/?match=1&clipping_id=170253439 Here's the bridge in question: https://www.bridgehunter.com/bridge/43115
The Frisco track chart and bridge record indicate that Bridge E-618.9 crosses the Washita River; no reference to Lake Tacoma is made. The bridge record is terse with regard to the bridge: One, 250-foot through riveted truss span, Eighteen, 39-foot deck plate girder spans, and Fifty one, 61-foot deck plate girder spans. The total length is given as 4057 feet; the track chart gives 4050.5 feet. Unlike other entries in the record, this entry is not sequential. The Flood Pool elevation of Lake Texoma is 640.0 feet. The track over the bridge maintains a naught.naught grade at an elevation of 649.5 feet.
Interesting post (I guess), but in order to access the newspaper link, you have to be a subscriber. GS
