at the moment my 2 bridges are just plywood planks with track glued (reliable operation was my primary consern). i have several ideas how to make those bit more realistic. however i'm for your ideas and input as well.
not sure exactly what i was going for, i guess i was under impression of old RR bridge in St' Paul , MN, i visited but both bridges are "see through" - i made a cutout in the middle of plywood plank. that can be closed if so needed. i was thinking canibalaising some C83 flex or even C55 N scale flex track to create guard rail in the middle for both.
short bridge.
that one i guess i could "straighten" out. from what i see prototype bridge for curved track is usually straight but wider to accommodate the curve. then either add shallow truss from below or above. or make it into "tub bridge": add two sides, close from the bottom and fill with ballast...
long bridge
that one the only idea i have is to call it a concrete box girder bridge. shave and paint the ties gray concrete. clearance from below is critical so o wouldn't extend it down more then few milimeters (for the girder)
your input is welcome
