A joint venture (JV) comprising Astaldi Group, Ghella, Oberosler, Cogeis and PAC has secured a €1bn contract to build the Italian stretch of the Brenner Railway Tunnel.

As part of the deal, the JV will build an exploration tunnel and two main tunnels from Mezzaselva in Fortezza to the Italian border with Austria.

A total of 23km will be dug for the development, with 46km excavated using tunnel boring machines (TBMs). 

Construction work is estimated to be complete within seven years.

"Once complete, Brenner Tunnel will be the longest underground railway in the world."

The company said that the formal signing of the contract ratifies the beginning of works and follows a preliminary agreement awarded in March.

Astaldi Group CEO Filippo Stinellis said: “The Brenner Tunnel, once completed, will be the longest underground railway in the world.
