plate girderbridge h.o.scale railroad ties (thicker)

Does anyone sell a dual track Plate Girder Bridge in code83 even in a kit or do you just use two next to each other. I've seen multiple track bridges in the northeast but I can't seem to locate am HO one
I came across one for sale not yet used. Walthers cornerstone series plastic model of steel
plate girders double track. really nice plenty of rivets. I liked it so much I bought a brand
new one and spliced it into with the used one(not yet built. That gave me the proper length I
needed. The opening above the track looks it will be able to work with the taller newer loads
one see's on the railroads today. Very sturdy looking span.
You'll have to use your own track though. I would suggest getting the style track that
has the thicker type railroad ties. Regard's,tr1
Good luck!
