Breakthrough of the Vadlaheidi tunnel in North Iceland

The blasting of the last three meters sepa­ra­ting the eastern por­tal from the western por­tal was cele­bra­ted in pre­sence of the tun­nel "godmother", the con­struc­tion super­vi­sion, poli­ti­cal repre­sen­ta­tives and many guests on Friday, 28th April 2017.

The driving operations on the 7'170 meters long single tube road tun­nel with a bore cross-section of 65 m² star­ted on 3rd July 2013. Since then, the miners have over­come con­si­de­ra­ble chal­len­ges, such as the filling of more than 30 liters per second of a 60°C hot water fis­sure, or the 500 liters per second of cold water pouring in from another fis­sure, as well as the high varia­bi­lity in the geology.

Thus, the cele­bra­tion of the break­through and the accident-free driving opera­tions was even more jovial.

The tunnel will be put into operation in 2018, reducing travel between Akureyri and Myvatn by 16 km.
