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.
Following requests for submissions from all over Europe, the Deutsche Bahn commissioned The Tunnel Rastatt JV, with the technical management in the hands of the Ed. Züblin AG and the Hochtief AG responsible for the commercial side of things, to undertake the roughwork for the tunnel at a cost of 321 million euros. Work commenced in November 2014 with the creation of a site installation yard at Ötigheim and the building of the north groundwater trough, the access to the tunnel’s north portal.

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.
As in previous years, the STUVA also undertook a survey of current tunnelling projects in Germany at the turn of the year 2013/2014. The outcome is compiled in tabular form for the month of December 2013 and subsequently assessed. The table follows up its predecessors published for the years 1978 to 2013.
Within the scope of the opening press conference marking the InnoTrans 2014, the world’s largest fair for transport technology, Dr.-Ing. Roland Leucker, the STUVA CEO, emphasized that tunnels only represent a small part of the infrastructure but nonetheless a highly important one. After all, tunnels often make the efficient use of high-speed routes possible. He provided the journalists present an overview of the advantages, which result if the required infrastructure is placed underground with lucid examples for increasing the need for mobility and cutting down on travelling times.
A new publication in the so-called “Blue Series” from the Association of German Transport Companies (VDV) appeared punctually marking the InnoTrans. The book was handed over to Federal Minister of...
