at least it's a truss, not a UCEB.
I meant to get back on this one. Yeah Nathan your right about there being no v-lacing and such. The thing that got me is the bridge being a modern one lane through truss. But the trusses being made of solid beams makes it not look exactly like the old bridge. I like to see a historic bridge in its original location open for what it was built for. But this cant always happen. The historic truss bridge should be moved and not destroyed. If thats the case and a county or whoever wants a modern through truss, this Bach Steel should be put to work to build a modern through truss with the v-lacing and other historic details.
I agree with Nathan here, the bracing is not present, and I also notice a lack of rivets.
That's only true if a company is not set up to do them and most of the industry isn't. With the right contractor and the right spec. a cost effective approach to a much better result is achievable.
Can't please everyone I guess would be the short answer. Rivets and bolts are not really modern or cost effective building materials.
You can't have your cake and eat it too.
Am I looking at the same photo/bridge? The new bridge looks nothing like the old bridge! The most glaring difference is the lack of v-lacing, so instead of intricate geometry and an open-air appearance, you get solid beams.
Next time get Bach Steel www.bachsteel.com and their engineers to rivet together a nice looking modern bridge that pays true homage to the historic bridge and fabrication methods. Or even better, select an available historic bridge for relocation and reuse. A 1930s era truss bridge for example would be able to offer much increased roadway width and load capacity, much like the modern truss seen here.
Now, I would normally bash a modern covered or metal truss being constructed to replace a historic bridge being demolished. Well, since the old bridge is being saved, I'm alright with this modern truss bridge. It looks so much like the old bridge and the portals are more neat than plain. As long as a historic bridge is not demolished, I wish more modern metal truss bridges were constructed rather than UCEBs. Truss bridges have more character.
