Use this bridge set to have a highway overpass above your trains. The "short" piece can be used as is, and the longer piece is designed to that multiples can be glued together. In the pictures above, the long bridge is two pieces connected, with one end cut off at the edge of the layout scene.
Print as many pillars and/or abutments as you need.
I used thin styrene for the road surface, cut to fit inside the guard rails.
Supports:
Are needed for the long piece, due to the overhang connector pieces.
I printed the pillars upside down to avoid the need for supports.
Everything else prints as-is.
