Hi TJ Seems to be the bridge with the best weight to span ratio - great. Do you know the pc game 'bridgebuilder'? It lets you build truss bridges but with a limited amount of money (= beams). looking forward to your stay in Switzerland Beat (20 years ago, 4-Apr-04, to lugnet.technic, lugnet.trains, FTX)
