Re: Chama bridge trivia

This gets more interesting. From copies of materials obtained from the RW Richardson library at the CRRM while researching bridge 377B at Navajo, I see the "General Plan and Details of Masonry Bridge 377-B - 4th Div." dated 7-27-23 notes the span to be "From Br. 380-A, No. Fork Br" and shows the span 120 feet between bearings. So it looks like one of the 120 foot spans from North Fork 380A ws slated to ended up at Navajo.
Another document which lists bridges "Alamosa Division - La Veta to Durango - MP 190 to MP 451" shows Bridge 343A crossing the Chama River consisting of two spans, one of 120 feet, the other 110 feet, both originally built in 1888 by "N.J. Steel and I." (New Jersey Steel and Iron?) and placed over the Chama River in 1924. The remarks column says both spans were "From 380A N. Fork Br." The same document also shows Bridge 377B to be a 120 foot with same build date, builder and remark as the for the Chama bridges.
A third document "Steel Bridges To Be Replaced" inlcudes a listing for 2 spans of Bridge 380-A at 120 feet each and 1 span of Bridge 380-A at 110 feet built in 1888 of iron. A "where to be used" column in the chart has one of the 120 foot spans noted as "343-A 4th Chama R" and the other 120 foot span as "377-B 4th Navajo R". The 110 foot span is noted as "343-A 4th".
So it looks like three spans from 380-A on the North Fork migrated to a second life on the San Juan Extension sometime in 1924!
Not that any of this has actually motivated me to start building a model of Bridge 377-B to replace the section of spline that carries the track over my bare plywood Navajo river bottom yet. Dave Dye's photos provide some real inspiration though.
