After a two-year construction period, the breakthrough of the first tube (western tube) of the Oberau Tunnel (Germany) was celebrated on November 17, 2017, at 10 p.m.
The 3 km long western section is part of the Garmisch-Partenkirchen bypass. After completing the construction works, scheduled for 2021, the Oberau Tunnel will be the longest twin-tube road tunnel in Bavaria.
The EUR 230 million bypass shall divert traffic going to the holiday destination of Garmisch-Partenkirchen around the village of Oberau.
