Glen,
Great information! The picture looks like a 45', a 30', a 70', a 30', and
finally a 45'. There do appear to be one concrete trestle on one side and
two spans on the other side. The different depth of each of the different
size deck plate girders is what gives it an "unusual" appearance. I
appreciate the confirmation!

I don't have a copy of the book so I don't know what the 1990 photographs
show. Q alignment charts from the early 1950's and the mid-60's both show
a bridge containing three 16' concrete trestle spans, two 30' deck plate
girder spans, two 45' DPG's, and one 70' DPG. These span lengths agree with
the total length of 270 ft. that I show in my old bridge records. I don't
know the correct order of the spans, but I may have other records that show
span orientation, and I will look for them. In the meantime, you may be
able to compare the above span descriptions with the photographs you have to
see if there is some correlation.
The Q bridge was older than 1950. There was a line change in 1948 from
the east end of curve 133 to about the middle of Burke siding, but the
original line was used over Johnson Creek and the other bridge just west of
it.

Subject: [CBQ] Bridge over Johnson Creek
Looking for some help from the old heads. I just received a Four Ways
West book called Windy City to the Twin Cities. It's a BN book covering
the Q
territory. On page 50 there are two pictures of a bridge over Johnson
Creek just a few miles east of the Burke siding - a steel girder bridge -
with
a what seems to me a different arrangement of girders and decks. Can
anyone tell me if this bridge had been built before 1950? It looks like an
old
structure, but the pictures were taken in the 1990's. I'm trying to
determine if I can model this as the pictures show back in 1950.
Thanks,
Rich G.
