There is a way of achieving a single curved span, but it'll take some work and some thinking out.
Basically, at each abutment there will need to be an arm at base level that extends to the same distance as the greatest point of the arc to prevent the overturning movement. The bridge will need to be fixed down to the abutments to stop it kicking up when the weight of the train is in the middle.
As this plan view.
