I needed another bridge. I have two home made country bridges but really wanted an old rusty looking girder bridge. Down the road I want to add a railway line onto my table top so a girder bridge would be perfect for that. Dapol make a very cheap range of plastic terrain aimed more at railway modellers. Their buildings are too small for 1/72 scale wargaming, in my opinion, but this bridge is perfect. It is 32cm long and wide enough to take a medium tank (Sherman etc). It makes it easy on creating a rule for what weight it can withstand. If the tank is too wide for the bridge then it is too heavy for the bridge.
I think I bought this direct from Dapol at their web site Dapol Girder Bridge
It is a simple model, with three main bits, two sides and a bottom. Plus some struts to link the tops. There is some decent detail showing lots of rivets. I had a lot of fun painting this up. A solid undercoat of matt black, then a spray of red brown. Then i attacked it with buckets of track rust and light rust weathering powders. Using a really wrecked brush i stippled more black back on top, plus a wash of brown on top of that. I think I even went again with more rusty powder. I wanted a really old rusty effect so spent some time adding more and more. The colour and texture came out quite nicely and even looks like peeling paint in some places.
I also made some quite steep roads for each end so I can place my bridge over a river. I used polystyrene on MDF bases coated with plaster for good strong and light results.
