The 130x8 bearing bar rests on a steel frame embedded in the perimeter wall of the Rio, and was designed to bear the excess weight of even the heavy vehicles that run along the road. The special feature of this application was that a curving, sloping grating had to be designed, and therefore subject to different sorts of torsion, particularly when the load is in the middle of the grid. An exceptional piece of work that protects the natural course of the Rio while making the Cloz road far safer and more functional than it had ever been in the past.
