If it's construction it's either concrete or steel anything else not my business
I know where there's plenty of aluminium bridges. Like dozens of them...
It's just "use steel and if you're not using steel why aren't you using steel? are you a poof or something?!"

Yep plenty of bridges made from ally!!
Search br90 I worked on that project for vice years!!
Amazing bit of kit!!
Vickers engineering in Wolverhampton were trying to replicate the bridge but using carbon fibre for the majority of it
I guess mobile bridge systems are a bit different, in the sense I'm guessing their budgets and specifications required are different to a standard steel truss

But anyway enough about bridges, thinking john1.4's design is looking pretty spot on. Simple enough but looks strong enough
