So, was it even necessary to add a temporary modern bridge to site dedicated to historic bridges?

Kinda waters things down unfortunately!

It certainly was an Acrow Bridge. I work for Acrow. Here's a link to the case history on our website: http://acrow.com/acrow-case-study/temporary-multi-span-panel...

My understanding is that Acrow modular bridges are essentially Bailey truss bridges, updated and simplified. They call them the "Third Generation" which I assume means an improvement over the original Bailey M2 Model. Basically Bailey 3.0. From BridgeWeb.com:

The 700XS Acrow Panel Bridging system is the third generation of improvements beyond the original, world-renowned Bailey Bridge. Briefly, the design of the new 700XS System has produced a lighter bridge comprised of fewer components with a truss that is 50% taller than alternate panel bridges and, as a result, 50% stronger in bending and 20% stronger in shear.

Does anyone else thing this looks like an Acrow bridge rather than Bailey?
