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.

More about the NRLA

The construction of the New Rail Link through the Alps (NRLA) will give birth to an efficient high-speed rail route with the two Gotthard and Ceneri Base Tunnels at its heart. The new rail link with its wide curves crosses the Alps with minimum gradients.

Shorter journey times

The flat route enables efficient rail transport of goods and reduces domestic and international passenger journey times. The new routes cut passenger travelling times substantially. The new 60-km high-speed Gotthard line has no tight bends or level crossings on the overground sections, meaning that passenger trains can travel at top speeds of up to 250 km/h.

Switching from road to rail

The railway infrastructure must be modernised and extended in order to improve public transport and transfer as much goods traffic as possible from road to rail. 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.

The Gotthard Base Tunnel is scheduled to come into service at the end of 2016, and the Ceneri Base Tunnel at the end of 2019.
