Description 

While this bridge may look like an historic truss bridge, a look underneath reveals that it is actually a modern concrete slab, complete with intermediate fake stone piers underneath and the incorporation of the original trusses to show some idea of what was here previously. It's nice that the trusses and bracing were retained, but the flooring system was lost completely, rendering the historic value of the original bridge as moot. The trusses are very beautiful and elaborate, with plenty of V-lacing and lattice to keep the eyes busy. The trusses have had identical parts fabricated to extend their lengths to accommodate the longer slab bridge.

It is modern engineering to be sure. All our modern computers, construction materials and equipment, and it takes four spans to cross this obstacle. Way back in 1891... they did it all in a single span!

As a note, I added two photos of this bridge before its replacement occurred. The original bridge was a bit shorter than its replacement.

HMMM, would truss bridges that have been modified so that the trusses are no longer functional also fit into this category? The Merriam Street Bridge, just a few blocks away from this one, is an example of this. Not a full bridge replacement, but still a blow to its historic integrity.

We could almost add a category for "Modern Bridges Masquerading as Historic Structures."

Well, now I know of two for this category, anyway.

Wow, Matt! I go over that bridge all the time & never realized it wasn't an old bridge. Here I was giving Mpls lots of credit for saving an old span-shows you what I know!
