Yes, those were a couple of the bridges I was thinking of. I don't know which company built the lattice spans on the Pegram Truss. Edgemoor might have, but their involvement may have been limited to the center span.
And the outer spans of this one as well...

Looks like some shared heritage is a good possibility on those two!
Robert Elder suggests that this bridge resembles one from mid Kansas. Comparing portal braces it may be along the lines of:

Valkommen Trail Smoky Hill River Bridge
This bridge is extremely similar in design to the railroad bridges on the UP line in central Kansas. Whether it was moved from the Midwest is hard to say, but the builder is almost certainly the same.
That is the thinking that the two lattice spans were relocated. From where is the mystery. The government constructed the line to service the Hanford Nuclear Reservation. Perhaps another railroad had two available lattice spans to complete the crossing.
Very nice bridge! Am thinking the 1950 plate and date refers to when the girder spans were fabricated. The lattice spans are likely older. Maybe they relocated the lattice spans here and paired them with new girder spans?
I'm glad to see this structure finally listed. I spotted it on a drive by last spring, but did not have the time to stop. As always nice work K.A.
