On September 22, 2020, the Gubster tunnel will be penetrated, which is a very important day for miners.

The milestone of the project has not yet resolved the traffic congestion in front of the Gubrist Tunnel, because after the breakthrough, the interior of the tunnel will be completed with the construction of the lanes and the installation of operation and safety equipment. Astra is expected to open the third pipeline to traffic at the end of 2022. After that, two existing two-lane Coopers pipes will be refurbished in phases. The expansion of the Zurich North Bypass is expected to be completed by the end of 2025.Editor/Luo Wentao
