In my HO layout, I plan to make a track that is constantly on a wooden bridge. It has to make a 15" radius corner and do some other maneuvers. How would I make, or where would I buy a bridge like that?[?]
Campbell makes a few different wooden bridges, but I don’t know about 15" radius turns. That is kind of tight.
these follks have some cool products

MRR has a book on bridges that will tell you how to do it.
In MRM or Walthers there is a template for building a wooden structure. It allows you to get the bents aligned on you radius.
Cheap way is:
- Yard stick Drill hole at 1", 16" (center of curve) then if 2" wide 15" and 17".
- Roll of brown paper.
- Draw the plan on the brown paper then build your bridge using that as a template.
There are many drawings avaiilable just google bridges nad such.
Sounds like a neat project, good luck.

P.S. I am using the CHEAP WAY for all my bridge layouts.
Could portions of the track run on ballasted deck or viaduct? Would simpify the amount of tressle. The 15" radius is real tight even if it were HOn3. Because of such a small radius, the sections of staight beams between bents will have to be fairly close. Also if you are not hand laying the track, check out the Micro Engineering bridge flex track. It is 36" code 83 w/ brown bridge ties and comes w/ code 70 guard rails, fire barrels and guard timbers.
ME has no web site, you have to order from LHS (Walthers) or call them directly as I do.
Maybe others on this forum can give you some info/ web site for the construction details.
