route in between Aarhus Moen in Seljord Municipality and Gvammen in Hjartdal municipality in the Norwegian Telemark region. The tunnel was opened to traffic on 19 December 2019, and at the same time the old road via Flatdal, \u00c5sebrekkene and Ambj\u00f8rndalen was converted into county road.<\/strong><\/p>\n<p><iframe loading=\"lazy\" style=\"border: 0;\" tabindex=\"0\" src=\"https:\/\/www.google.com\/maps\/embed?pb=!1m14!1m12!1m3!1d64681.67516756008!2d8.688735470832778!3d59.56137253341924!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!5e0!3m2!1sde!2sat!4v1606983042978!5m2!1sde!2sat\" width=\"600\" height=\"450\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" aria-hidden=\"false\"><\/iframe><\/p>\n<h4>History<\/h4>\n<p><span class=\"goog-text-highlight\">The E134 is the shortest road from Drammen to Haugesund, and one of the main road connections between Austlandet and Vestlandet. Through Telemark, the road has poor standards in several places, with narrow roads, steep curves and large inclines. Especially between Gvammen (Hjartdal municipality) and \u00c5rhus (Seljord municipality), there were stretches that present significant challenges for accessibility in winter, such as Ambj\u00f8rndalen and Nutheimkleivene. Through Hjartdal and Flatdal there are also a good number of houses along the road and many exits.<\/span><\/p>\n<p><span class=\"\">The rerouting of the road through the tunnel from Gvammen to \u00c5rhus shortened the E134 by approx. <\/span>11 km. In addition, the new road is almost flat, and this together reduced the driving time for heavy vehicles by about 18 minutes.<\/p>\n<p>The 9,355 m long <span class=\"\"> M\u00e6lefjell Tunnel<\/span> is now the longest road tunnel in Telemark and the seventh longest in the country. A total of 11.7 km of new road was built, replacing 22.6 km of the previous route.<\/p>\n<p>The project was carried out in between 2013 and 2019. In April 2013, the first part of the work started by blasting out a rock cut along the then E134 to use the masses for preloading for bridge foundations, and other preparation and construction of supply roads to facilities and landfills. The main construction was started in November 2014, while the first salvo in the tunnel itself took place on 17 December 2014 on the Gvammen side and two months later on the Aarhus side. By New Year 2016, the tunnel had been blown out a total of 4204 meters; 2715 meters from Gvammen and 1489 meters from \u00c5rhus, and breakthrough was expected during the year. However, water leaks led to delays in progress. Finally breakthrough was on 3 May 2017.<\/p>\n<p><span class=\"goog-text-highlight\">In September 2017 the Norwegian Public Roads Administration and Aventi Installation signed the contract for the electrical works with a <span class=\"\">value of over 93 million NOK. After completion of the works the tunnel was opened for traffic on 19 December 2019.<\/span><br \/>\n<\/span><\/p>\n<h4>Blue light<\/h4>\n<p>In the M\u00e6lefjell tunnel, a couple of thousand LED luminaires have been installed. Still, over the long distance it is a bit monotonous not seeing other landscapes than the tunnel walls. To break the monotony blue lights have been installed.<\/p>\n<h4>Sensors from JES<\/h4>\n<p><a href=\"http:\/\/aventi.no\/\" target=\"_blank\" rel=\"noopener noreferrer\">Aventi<\/a> has chosen our distributor <a href=\"https:\/\/www.houm.no\/\" target=\"_blank\" rel=\"noopener noreferrer\">HOUM AS<\/a> to equip the <span class=\"\"> M\u00e6lefjell Tunnel<\/span> with sensors from JES. <a
