Leave the date as is, but change the history line ot "Relocated here 1957"

The site really needs a dedicated box for relocation dates due to the prevalence of bridges being relocated, especially the railroad relocations Daniel has shown in CA and John has proven in the Midwest

That's what I thought. What's the right thing to do, list it as moved to current location 1957 or remove the date entirely? I have no clue where it came from.

A relocation date? YES... A build date? NO WAY!

Given the pinned connections, is 1957 a reasonable date?

The design looks awfully similar to the 3 I looked at this past weekend, East of Merced: Oak Grove Road Bridge (listed as built 1912/rehab'd 1960), Mid Fork Chowchilla River Bridge (listed as built 1956), Speciman Springs Bridge

(listed as built 1958) Some differences are apparent: the ones I looked at have sway bracing at every vertical while this has it only at the portals, and this has more laced members, but I'd have guessed the same era and put it a few decades earlier than late 50s.
