Railway bridge over the Rio Vizze Creek (Italy)

The new metal truss bridge, which covers a span of 48.5m with a single span, replaces an existing three-span bridge that has reached the end of its life.

The main dimensions are listed below.

– Total length 49.40m
– Length at the supports 48.5m
– Height of the girder 10.33m
– Total width 12.20m
– Tank width in c.a. 8.78m
– Weight in the launch phase 109 tons

Bolina has developed on behalf of BIT SpA:

– The project of the dismantling phases of the existing bridge
– The assembly project of the new bridge
– The design and verification of ancillary equipment at launch

In order to carry out the replacement by interrupting the railway line only for a short period, the ground assembly of the new bridge was planned in the immediate vicinity of the existing one.
For the transport from the assembly point to the final project position, a double pair of SPMT trolleys was used
