More background and speculation here >
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...
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? :^)
