I have a very short part of my overhead trolley line that passes over the mainline below. To complicate matters, this overhead track is part of a 031 curve, so any of the traditional bridge options (that I am aware of) are not viable for this setup.
Do any of you have a similar situation or know of a product that would be suitable to construct my own bridge and accommodate this curve?

For short spans, I have successfully modified Lionel #314 steel girder bridges to use on curved sections. I drill out the rivets holding the steel sides to the sheet metal bottom. Cut a new, wider bottom sheet, and fasten it back onto the side pieces using rivets or #6 machine screws and nuts.
I have a local body shop cut me pieces of 20 gauge sheet metal to my dimensions for the new bottoms, but a piece of thin plywood would also work. I have also used two of the old bottom pieces, bolted together through the rivet holes in the middle, to make a double-wide. All depends how wide you need to be to make your curve.
Thanks Hojack! I have a few old girder bridges so will look into what can be adapted for this project!
