The early tied arch bridges were massive and indeed usually kinda odd looking. The lack of a straight upper chord led to some very creative ways to roof the structure. And from what I have read they were a nightmare to dismantle.

It was probably one of the earliest substantial use of iron in an American bridge... and most certainly an oddball bridge to be sure...

So Nathan,

This one is a bit or a conundrum, it's a wood covered bridge but it has a unique design that is essentially a bowstring with wood compression and iron tension members. Is this the long lost missing link or is it an abomination? :^)
