| Digging work completed at tunnel site in Greater Paris Area Digging work on the second section of the A86 Duplex tunnel linking Pont Colbert (municipality of Jouy-en-Josas) with the A13 motorway (Vaucresson - Le Chesnay) over 5.5 km was completed with the spectacular exit of the tunnel-boring machine at the level of the A13 interchange. This new stage, crucial in terms of completing one of Europe's largest construction sites, also illustrates a symbolic moment in the run-up to the inauguration of the first Rueil-Malmaison/A13 interchange section in the spring of 2008. The exit of the tunnel-boring machine from the A86 motorway heralded the end of digging work on the A86 Duplex, an innovative double-deck motorway tunnel covering a total distance of 10 kilometers, designed to guarantee maximum comfort and safety for motorists in the Greater Paris Area. In 2010, the A86 Duplex will link Rueil-Malmaison and Versailles, thereby completing the French capital's "super-ring road". As a result, this drive will require less than 10 minutes, instead of 45 minutes currently. The first section of the tunnel, between Rueil-Malmaison and the A13 motorway, is now in its fitting out phase and soon tests will be carried out prior to its inauguration scheduled for the spring of 2008. Completion of work on the second section of the tunnel between the South of Versailles (Pont Colbert) and the A13 motorway, will lead to the final link-up of the A86 between Rueil-Malmaison and Versailles by 2010. For Cofiroute, a subsidiary of the Vinci group and the concessionaire of the A86 Duplex tunnel, the A86 Duplex perfectly illustrates the success of the integrated concessionaire–builder model that has enabled its motorway network to be financed, built and equipped with facilities. With nearly €800 million invested per year to build new motorways, widen existing sections and improve the overall quality of its network, Cofiroute is now one of the leading players in France in town and country planning. write your comments about the article :: © 2007 Construction News :: home page |
