Salini Impregilo, together with STRABAG, Consorzio Cooperative Costruzioni CCC and Collini Lavori, has received a provisional award for the €300M contract to build an ‘underpass’ beneath the Isarco River – in the southern segment of the “Brenner Base Tunnel.”
The “Isarco Underpass” is the southern segment of the Brenner Base Tunnel, located in Prà di Sopra in Italy’s Bolzano province. Planned construction for the project will include civil works for the two main tunnels for a total length of roughly 4.3km, as well as two interconnecting tunnels for a total length of 2.3km that connect with the existing railway line. Construction will be extremely complex from a technical point of view: both the main tunnels and the interconnecting tunnels will pass beneath the Isarco River, A22 motorway, SS12 state motorway and the Verona-Brenner railway line with minimal leeway.
Work is scheduled to begin in the second half of this year, and continue for 8 years.
Salini Impregilo and STRABAG won the “Isarco River Underpass” contract just a few months after winning the principal “Tulfes-Pfons” contract in Austria (€380M). Tulfes-Pfons is the main segment of the Brenner Base Tunnel, part of the Trans-European Networks (TEN). The contract for the “Isarco River underpass” is the final segment of the important Brenner Base Tunnel project, at 64km the longest underground railway connection in the world and the primary element of a new railway line that will connect Munich and Verona, Italy.
