The Marieholm Tunnel in Gothenburg is a road tunnel with three lanes per direction and an evacuation tunnel. It is devised for more than 100 years service life and is to be built as an immersed tunnel just like the 300 m long, two-track Söderström Tunnel. Towards this end, three part-sections each 100 m in length are constructed in a dry dock and then submerged in a trench excavated on the riverbed.
By 2016 Maastricht intends relocating no less than 80 % of the existing volume of traffic on the A2 urban motorway underground. The “Groene Loper” (Green Carpet) project represents one of the biggest construction schemes ever undertaken by the city in the south-east of the Netherlands. At present a double-deck tunnel with two bores is being produced – the first of its kind in Europe. The new tunnel is largely being built by cut-and-cover, in 24 m long sections on average, with traffic flowing right past the site and close to built-up areas.
