Help. can someboy (or multiple somebodies) help me locate n scale bridges. I have been surfing manufacturer sites till I'm bonkers in the head and can't seem to find anything even close to what I am looking for - and I'm not even being that specific. I have a canyon crossing that is approximately 10" across at the top (183 N scale feet) though that can be fudged several inches longer but not shorter. At this point, I'm looking for anything that can span the gap without any pillars coming down in the middle. I did find one by Heljin but can not find any specs so I sent them an email.... waiting. It looks like I may have to build several from scratch. WHERE do you people find all these cool bridges I've seen? Thank you!
