Description

Traffic on the existing expressway at ground level (volume approx. 180 000 vehicles per day) was not to be Interrupted; it was therefore necessary to effect special traffic management measures, adopt special construction methods and, above all, carry out construction work at night.

Standard viaduct cross-section: a concrete deck slab on top of 10 T-girders placed on cross-beams which are supported by 2 arms of Y-shaped piers-both an aesthetic and an economical solution.

A prefabrication yard was set up near the construction site; because of the restricted working area there, off-site prefabrication was essential:

  • surface area: 6 500 m²
  • gantries: 1 X 140 t/2 X 70 t
  • workshops
  • site laboratory
  • main offices
  • 2 concrete batching plants (each with capacity of 60 m³ / hour)
