Italian contractor 1324 Astaldi has begun drilling two parallel tunnels as part of its S7 dual carriageway project in Poland.
Each tunnel, between Naprawa and Skomielna Biala and under the Lubon Maly massif, will each be just over 2km long.
Astaldi, based in Rome, won the three-year S7 dual carriageway project worth around €225 million in 2016
Work includes 38 bridges and viaducts and three motorway services. There will also be 25km of access roads and two junctions.
The north-south S7, when completed, will run 720km from Gdańsk on the Baltic coast through Elbląg, Warsaw, Radom, Kielce and Kraków to Rabka near Poland’s southern border with Slovakia. The vast majority of construction will be upgrading National Road 7 (DK 7).
The S7 is part of European route E77, in turn part of the inter-European road system, starting in north-eastern Russia and running 1,690km through the Baltic Sea states, into Poland and connecting with central Europe.
Astaldi’s highways division has been particularly active in Turkey – the Mount Bolu Tunnel, the Izmit Bay Bridge and, in Istanbul, the Third Bosphorus Bridge.
In 2015, Italian firm Salini Impregilo started construction of a 21.5km stretch of the S7 between the Jedrzejow and Checiny junctions under a deal worth nearly €144.67 million. Completion is set for the third quarter of of this year. Meanwhile, a consortium headed by Budimex won a contract worth nearly €318.28 million for the construction of a 9.7km section of the S7 between Ostroda Polnoc and Ostroda Poludnie.
In 2014, a Strabag consortium, picked up a €127.93 million contract for a 4.5km section of the S7 dual carriageway near Krakow, including construction of a bridge over the Vistula River.
