"A UNIQUE METHOD OF STRENGTHING A TRUSS BRIDGE" - Continued.

This sort of strengthening (support of the truss at panel points) has been used in quite a few places.  I would suspect that few would be as difficult as these two bridges.  
 
One I have seen is (maybe that is was) on the Tennessee Central and visible from I-40.  It was some 50 miles east of Nashville.  When this method is used, the truss itself becomes unnecessary.  It also begs the question, if multiple short span were OK, why was a long span considered necessary in the first place?
 
The truss elements could be removed after these supports were put in place if the railroad so chose.  Since I can think of several truss bridges that have remained in place after the railroad was abandoned and the tracks removed it could be that the value of the steel in the bridge for this size truss is less than the cost of removing the bridge.
