I was on Youtube and I found this video.
The bridge is at the end of the video.
This bridge is currently owned by Canadian National Railway (Wisconsin Central is merely a subsidiary unit of the company), who has applied to the Army Corp of Engineers for demolition of this, one of Michigan's longest truss bridges and one of our only lattice truss bridges. The bridge was originally built as a five span bridge and converted to a ten span bridge. It was originally built by Chicago and Northwestern Railway who liked lattice truss bridges. I have a few poor copies of original plan sheets for the bridge but haven't posted them online yet. I did post some photos for the bridge recently on HistoricBridges.org here: http://www.historicbridges.org/bridges/browser/?bridgebrowser=michigan/lattice/
It's actually a Quadruple Warren (Warren Quadrangular)truss that is found on a number of railroad spans.
Very nice bridge!
Bridge trusses look like a Whipple. Am I correct?
