Ah. That's interesting and pretty clever. The "sacrificial" beam is an easy way to access the main girder, though. Without it, taggers would either have to tag the inside of the girder facing the tracks (who cares) or they'd have to shimmy out onto the bottom flange, which would deter a lot of them. The fact that the girders have
already been tagged is evidence of this problem, which is gonna lead to a maintenance headache.
Besides - what happened to the clearance-raising part of the project? Did Metra drop that goal to save a few bucks? The comparison image shows some huge bearings on the previous plan that don't show up in the updated plan.
