I spotted this today when cycling across the Mississippi on the 3rd Avenue bridge, heading towards downtown Minneapolis.
A horizontal frame was protruding from the back of a road construction truck.
A rather agile cherry picker on another truck was conveying workers to the underside of the bridge.
I cycled to connect with a path that runs under the bridge. The workers appeared to be making a fairly rapid visual inspection of the underside of the bridge.
I could not understand the connection between these workers and the frame protruding from the truck above.
A Google search revealed the frame is a crumple zone to absorb a collision by an inattentive driver. The frame was there to protect the workers.
