One bridge...Two lines?

[AllenB]

Does anyone make an 18" bridge that will occupy two main lines? I can't seem to find one. If I have to go with two bridges, then I have to spread out my main lines a bit wider just for that purpose. This will be going over a river.

If you can not find anything, you may have to kitbash a couple kits together to get what you are looking for. Good luck to ya.

Say Alan,
Depend on what effect your looking for you might well be able to incorporate both ideas above from Frog and Charles.

You could use some Atlas Plate Girder bridges, they're just the sides to attach to a board of the required width to match the Truss bridge width with usually some type of support where they meet. You might have to section the Plate Girder sides to get the required length but you could have these leading into the Truss bridge on each side of it or have both on one side or the other.

The board they're attached to could be used to be a ballasted deck bridge which the trustle may be too?

Or of course you could construct several of the plate Girder bridges end to end to span the width between supports. Oh and the plate girders can also be used below to support as well as above if you have the clearance below?

So I hope this gives you some other ideas to toss around?

If the bridge is not exactly the right length, you could always use some short deck girders or trestle as an approach to the truss, kind of like what is happening here:

I thought Walthers had a double track truss bridge? If not I have seen two girder bridges built closly side-by-side

I ended up buying the Walthers although I've read some horror stories about it warping while trying to assemble. It's not quite the 18 inches I was looking for either but I think it'll do.
Thanks all!

I kit bashed two (or three) Central Valley girder plate bridges together for just that purpose. I was really stuck as I needed a curved double track bridge over a roadway, and couldn't find a suitable bridge that looked "American" enough for my layout. I was able to modify the Central Valley bridges to work on the curve (though I don't know if it would be quite prototypical). If you follow the street beyond the bridge for two blocks, you'll see part of the other side of the bridge (in the mirror in the upper left hand corner of the photo (the mirror starts in the center of the cross street beyond the bridge)).
It would have been real easy to make it a straight double track bridge. Then again, Central Valley might already make a straight double track bridge like this.

Glad you were able to find something. Post pics when you get a chance. Good luck to ya.

Better late than never but this beauty is a hair under 14", so you'd just need to fashion a pair of 2" approach ramps. See eBay item 140582208005

or you could do as the prototypes do and create a gantlet where the tracks overlap. see the section "Frog Gantlet" here:

That is too cool...I've NEVER seen anything like that.
