Track Spacing of MTH 2-Track Arch Bridge?

[SleeperN06]

So I kind of lost my head this Christmas train season and bought enough to start another train.

I’ve been desperately trying to figure out how I can add another track onto an already full layout. Then I a saw that MTH makes a 2-Track Steel Arch Bridge which would allow me to run a parallel track, but don’t know what curves to use to run around my existing 042 curve that would match up with the bridge.

Does anybody have that MTH 2 track bridge and be able to give me the info? I really would appreciate it, thanks.

I did a search on Google and found it on another forum. Just in case anyone else may be interested it is 4" according to this thread at
