Brian Austin Posted August 17, 2019 Posted August 17, 2019 Photos and historical info showing all types of bridges: https://bridgehunter.com/ https://historicbridges.org/index.php Drawings of a typical truss road bridge. https://www.bgstructuralengineering.com/HmwrkDwg/TBridge/Tbridge.htm Photos and old dimension drawings. http://okbridges.wkinsler.com/technology/truss.html#Members http://okbridges.wkinsler.com/technology/index.html http://okbridges.wkinsler.com/ https://www.loc.gov/pictures/search/?q=Drawing: wi0183&fi=number&op=PHRASE&va=exact&co =hh&st=gallery&sg = true https://www.loc.gov/pictures/search/?q=Photograph: wi0183&fi=number&op=PHRASE&va=exact&co =hh&st=gallery&sg = true 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. :-) https://www.worthpoint.com/worthopedia/lgb-5060-warren-truss-bridge-scale-1887200115
vincen47 Posted August 17, 2019 Posted August 17, 2019 Thanks for the resources. I’ve been to those sites before looking for info to use in model railroading.
Brian Austin Posted August 18, 2019 Author Posted August 18, 2019 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.
