China China's longest tunnel (Guixin, 8km)
The eight-kilometer-long Guixin tunnel will pass through the Beifeng Mountain and its highway will link with the outer round-the-city road of Fuzhou, capital of Fujian Province.
France A86 West Tunnel - Paris
The A86 West, when completed, will form the final link of the A86 ringroad around Greater Paris. At a cost of EUR2.23 billion the A86 West will be formed of two toll tunnels; one will be an innovative 10km double deck tunnel for light vehicles, the other, at 7.5km, is along more traditional lines with just a single deck designed for all vehicles including HGVs. Started in 1999 the project is scheduled for completion in 2007.
Le bouclage de l'A86 à l'ouest de Paris
10 kilomètres sur près de 80, sa longueur totale, manquent à l'A86 pour mériter vraiment son appellation de "superpériphérique" de l'Ile-de-France et assurer efficacement sa vocation : soulager le boulevard périphérique parisien, faciliter les déplacements entre banlieues, alléger la circulation sur les voiries locales. Le bouclage de l'A86 consiste à relier, en souterrain, Rueil-Malmaison et Versailles.

Germany Europe's longest construction site
Work is under way over the whole length of the 219 km high-speed railway line between Cologne and Frankfurt, making it the longest construction site in Europe.
TRIBUNE No 9: Focus on Germany
The Engelberg base tunnel - Leonberg/Stuttgart
Rennsteig tunnel 7.9 km, will become the longest road tunnel in Germany
Größtes und aufwändigstes Bauwerk im Zuge der Kammquerung des Thüringer Waldes ist der Tunnel Rennsteig. Mit 7916 Metern Länge entsteht hier der mit Abstand längste Straßentunnel in Deutschland.
Burgholz tunnel
Die südliche Röhre des Tunnels wird eine Länge von rund 1865 Meter, die nördliche Röhre rund 1787 Meter haben.
Stuttgart 21 is the first in a series of "21 Projects" undertaken by Deutsche Bahn AG (German Rail) which are based on one common basic idea: Towns and cities benefit from the modernisation of railway facilities and station areas.

Japan The Tohoku Shinkansen extension
Works have commenced on the Hakkoda Tunnel (26,455m) in addition to the Iwate tunnel (25,810 m) which is now at the peak of construction activity.
Nederland Westerschelde, subsea tunnel, 6.6 km
In 1986 a new plan for atunnel under theWesterschelde was developed. The initial plans were for a bridge combined with an immersed tunnel but the design was later modified to a bored tunnel, as this was cheaper. On the basis of a report on potential routes and an environmental impact statement the Provincial Council of Zeeland and the Minister of Transport, Public Works and Water Management selected the route between Borsele and Terneuzen.
Tweede Benelux Tunnel, 1995-2002
De bestaande Beneluxtunnel wordt meer dan verdubbeld. De nieuwe tunnel bevat niet alleen een autosnelweg, maar ook een buis voor de metro van Rotterdam naar Schiedam en een buis voor fietsers.

South Africa Lesotho Highlands Water Project, Mohale Tunnel
After excavating through the basalts of Lesotho for 16 km at 4.88 m diameter, this NFM Boretech Mitsubishi double shielded machine will enter the chamber to be dismantled underground and removed from the tunnel. Final lining of the chamber, cleaning and finishing the tunnel as well as M&E works will proceed during the rest of 2003. Thereafter the Mohale tunnel will be available to transfer water from the Mohale Reservoir to Katse Reservoir.
Sweden Södra Länken är Sveriges största vägtunnelprojekt. Den förbinder Essingeleden i väster med Värmdöleden i öster. Den gör det lättare för kollektiv- och biltrafiken att komma fram samt minskar genomfartstrafiken i Stockholms innerstad. Trafikleden är 6 km lång och av dessa går 4,5 km i tunnel.
Linking Malmö Central Station to the Öresund Fixed Link
The City Tunnel via Malmö will be completed by the year 2005 at the latest. A new two-track railway line will traverse central Malmö below ground for six kilometres, four of which as a bored tunnel.

Gotthardtunnel, AlpTransit Home Page
Der Gedanke, einen Gotthard-Basistunnel zu bauen, ist nicht neu: Eine erste Idee wurde bereits 1947 vorgelegt. Ein halbes Jahrhundert nach dem ersten Projekt von 1962 soll der längste Eisenbahntunnel der Welt tatsächlich in Betrieb genommen werden. Die 50 Jahre sind am Projekt natürlich nicht spurlos vorbeigegangen.

Lötschberg base line, Front Page
Construction Concept of the Lötschberg tunnel
The lateral adits of Mitholz, Ferden and Steg will serve as intermediate working points. These, together with the portals at Frutigen and Raron, will give a total of five working points. Given the sub-division of the tunnel as a whole, all bores will be less than 10 km long.

United Kingdom The Channel Tunnel Rail Link
The Channel Tunnel Rail Link will be Britain's first major new railway for over a century – a high-speed line running for 109km (68 miles) between the Channel Tunnel and St Pancras station in London. The project was authorised by Parliament through the Channel Tunnel Rail Link Act 1996. Section 1 has been under construction since October 1998 and runs between the Channel Tunnel and Fawkham Junction in north Kent. The first Section is on schedule for opening in October 2003. Work on Section 2 began in July 2001 and completes the new line into London's St Pancras. Section 2 is on schedule for completion by the end of 2006.
Department for Transport
One of the most important infrastructure projects presently being taken forward as part of the Government's Public Private Partnership (PPP) programme is the Channel Tunnel Rail Link (CTRL).
USA TRIBUNE No 8: Central Artery Tunnel
Central Artery/Tunnel Project (The Big Dig), Boston, Massachusetts
The Central Artery project has enough engineering marvels to fill a textbook. The designers and builders of the project are faced with difficult soil conditions, tight working spaces, the proximity to construction of huge glass and steel office towers and fragile old brick buildings, the need to hold up an elevated highway while tunneling directly beneath it, and generally keeping Boston open for business throughout 14 years of construction.
