Sliding the Cavalcavia Bridge
The operation formed part of the AltTransit
project to build a New Railway Link through the Alps (NRLA). Significant
modernisation work is underway to prepare for the high-speed line, with
the aim of improving public transport and transferring as much goods traffic
as possible from road to rail.

Cavalcavia Bridge - Switzerland
| |
Freyssinet was therefore called in to slide the Cavalcavia Bridge, which
lies on the path of the future railway line. The structure, weighing 6,000
tonnes during the sliding phase, was moved on X-slide pads using Hebetec
4H-200 and 4H-400 jacks. It took four hours to cover the 14.46-metre
distance.
The Gotthard axis of the NRLA is Switzerland's largest-ever construction
project. By building the new Gotthard line, Switzerland is undertaking
one of the largest environmental protection projects in Europe, as the
flat route helps to protect the Alpine region.
