As far as construction details this is where it gets "potentially abstract"!
Your bridge will be custom made for your layout, your height - your width and your length. Yes, you can build this any width, want to run 1 N gauge track, or 1 HO?? Make it the width of the 2 X 4 support, heck just use the 2X4 for the base. A 2 X 4 is nominally 1-1/2 X 3-1/2 you can definitely fit 1 single track on 3-1/2". But remember you can also turn the 2 X 4 vertically and use the 2" side.. (Nominally 1-1/2"
You just have to decide what is best for your layout.
