FYI, garden railway (i.e."G Scale") pioneer LGB produced a small truss bridge that might be adapted for use as a single-lane road bridge.  Note that the deck between the raised walkways is about 3-1/2" across, according to ebay listings.  Length is 450 mm.  Note that this would represent a type of bridge that would exclude large trucks.  :-)

Thanks for the resources. I’ve been to those sites before looking for info to use in model railroading.

I've been using Bridgehunter to find bridges to photograph.  And it isn't even just the hardware that's interesting.  The way each bridge fits in the landscape, along with whatever they're crossing, is unique from site to site.
