Enlarging the third picture looks like both end spans are 9 panels long, while the middle span is seven.
Thanks for that. I design ships, not bridges!
A small correction, if I may--definitely not a lenticular, but not a double-intersection Warren, either. This is what is known as a "Quadrangular Warren" truss, or "quadruple intersection Warren", if you will...opposing diagonal members cross each member 3 times to divide each member into four segments; hence the Quadrangular name. Double intersection Warren trusses are named because each diagonal is crossed by the opposing diagonal only once, dividing the diagonal into two segments. These are common in New York, crossing the Erie Canal. Hope this helps!
Close but no cigar. This bridge is a double intersection warren or "lattice" truss. Lenticulars have a featured "eye" shape, hense "lens" = "lenticular". Look at spans such as Pittsburgh's Smithfield Street Bridge or the five span example in Binghamton, NY. Those spans are true lenticular trusses.
