After more than a year of tunnelling, the second bore of the 8320 m long Gleinalm Tunnel, the third longest road tunnel in Austria, was broken through in the middle of 2015. After the planned completion of lining work in autumn 2016, the east bore should be opened for traffic in 2017.
The two shafts that will allow tunnelling to proceed towards Gloggnitz and Mürzzuschlag are now being built at Lot 2.1 of the Semmering Base Tunnel in Fröschnitzgraben, Austria. At the end of July Federal Minister Alois Stöger, State Governor Michael Schickhofer, State Councillor Karl Wilfing, CEO of ÖBB-Holding AG Christian Kern and, representing the construction consortium, the Head of Implenia’s Business Unit Infrastructure Rene Kotacka celebrated the start of work on the shafts with invited guests.
Crossrail’s final tunnelling machine, Victoria, is being dismantled 40 m below Farringdon in central London following the completion of Crossrail tunnelling.
On July 10th 2015, the European Parliament confirmed the European Commission‘s 13 billion euros CEF (Connecting Europe Facility) infrastructure investment plan. 1.18 billion euros of these funds are earmarked for the Brenner Base Tunnel, which is thereby the most heavily funded infrastructure project in Europe

Seen from the fire service’s point of view, the risks in tunnels mainly result from the
necessary penetration depth. The expected heat load affecting fire services on the other hand is of a secondary nature. Consequently, the chances for successful deployment are largely determined by the distance between the emergency exits.
Heat in the ground can be exploited by energetically activating structures in contact with the ground, e.g. tunnels. In the course of the upgrading of the railway route from Munich to Verona, a part of a tunnel in the area of Jenbach in the Tyrol has been thermally activated in order to supply geothermal energy to the nearby utility centre.
The construction of a gas pipeline passing through a coastal nature conservation area was essential to exploit a gas field in the Atlantic. The gas is then processed in a facility on the Irish north-west coast. It was decided to thread the pipeline through the specially devised Corrib Tunnel so that the nature reserve could be underpassed without harming the environment. The tunnel was completed along with the operational gas pipeline in early 2015.
