Another bridge track question

Model Railroader General Discussion (Model Railroader)

I have seen an old photograph of a wide trestle with enough room on one side of the track for an automobile or small truck.

Obviously that trestle would have a solid deck but would it use bridge track or would the ties be the regular ones?

thanks

I can’t see them using anything else, just adding planks over the exposed ties.

At Agematsu in the Central Japan Alps the Kiso Forest Railway crossed the Kiso river through a truss bridge (wording deliberate.) Old photos show the usual bridge ties and open floor structure. More recently (1950-ish) the deck was planked solid to the rail tops for the convenience of rubber-tired vehicles. The original structure wasn’t modified, just covered over.
