Looks like on the center of the bridge they have an American flag that lights up at night.
Essentially just looks like a massive caisson/lolly column if you ask me.
I have to agree with Mr./Ms. Anonymous. I believe the center pier was cast in place just like the fixed span columns.
From what I've seen on this web site I think the central pier was always encased in steel.(iron ?) Anyway, beautiful bridge.
My guess is that the central (turntable) pier is masonry, but that it began to deteriorate and was encased in steel plate. Comments?
