On 24.05.2017 a final blast marked the event to celebrate the top heading breakthrough of the second tube of the 3-km-long Perjen Tunnel on the S16 Arlberg Expressway between Landeck and Zams (Austria). Only three weeks later, the breakthrough of the bench occurred on 14.06.2017.
As soon as the new second tube of the Perjen Tunnel will be completed in 2018, traffic will be transferred from the existing tube to the new tube. Starting in 2019, the existing tunnel will be closed for rehabilitation after 33 years in service and will be opened to traffic again at the end of the same year.
After rendering the overall design for the first tube, ILF has been awarded a contract by ASFINAG in February 2016, entrusting ILF with carrying out the geological documentation of the second tube.
