Cosidering using one one the layout but need some info before purchasing. What are the track centers on the bridge? How easy/difficult would it be to make em 2.5"? How wide is the bridge? How mych of the span is “clear” after adding abutments? And (opinion) does it look like it could support it’s span without the center posts?
I have a double track main that crosses over 2 spurs and one spur has a turnout under the bridge. I need at least 12" based on a width of 5". Since they don’t cross at right angles a wider bridge needs a longer span. Rough sketches based on advertised dimensions and pics show that the length is good and a guess at the width says not too wide, I may even be able to use the support posts but that is very dependent on clearance to the lower tracks.
Worst case, I may have to go through truss.
