Bridge Beam Steer Trailer Hauler Truck

A most amazing type of truck has been working for the last week transporting huge 100 foot long bridge beams from their storage site to the construction site where a bridge is being erected.
The "Steer Trailer Hauler" is a sight to behold as it rolls by with its 42 oversized wheels spinning.
The driver controlling the 22 wheeled rear portion of the rig seemed to be having a great ride when he passed me with a smile, wave and thumbs-up.
It was a pure delight to watch this truck negotiate a tight 90 degree corner much like a circus contortionist "Transformer Bot".
