Main contractor on the job is Bouygues, which was awarded the work from Tyne and Wear Passenger Transport Authority last year.
The new Tyne Tunnel will run parallel to the existing Tyne Tunnel between East Howdon on the north bank of the River Tyne and Jarrow on the south bank of the River Tyne. The new tunnel will carry all southbound traffic, whilst the existing tunnel will carry all northbound traffic
Volker Stevin’s work will start with the construction of the concrete tunnel units at the dry dock in Wallsend, Newcastle-upon-Tyne this summer.
There will be four 90m-long split sections of rectangular pre-cast and reinforced concrete tunnelling that are 8.5m by 15m.
The tunnel sections will be built in the dry dock before being floated down the Tyne adjacent to the existing tunnel where they are expected to be submerged in autumn 2009.
Volker Stevin managing director Paul Roebuck said: “As a local contractor we are of course delighted to be working on what is one of the biggest civil engineering contracts ever awarded in the north east of England.”
