The Lopper , a mountain in the Swiss canton of Nidwalden , is a southeastern branch of the Pilatus ( Emmental Alps ).
situation
The Lopper forms a narrow peninsula to the Vierwaldstätter and Alpnachersee . Its ridge reaches a height of 961 m in the Haslihorn . Its flanks are unstable and drop steeply on both sides up to 500 meters to the lakes. Numerous rockfall nets and barriers protect the north-south axis between Hergiswil and Stansstad , which runs close to its north foot .
The Lopper ends at Acheregg - here bridges to Stansstad cross the water that connects Lake Lucerne with its branch of the Alpnachersee.
Traffic routes on the Lopper
The construction of the first road around the Lopper was funded by the federal state of Switzerland founded in 1848. In the summer of 1861, stagecoaches were able to travel from Lucerne to Obwalden and over the Brünig Pass to Brienz for the first time. Until then, Obwalden could only be reached by land from Lucerne via the footpath of the Renggpass ( 886 m above sea level ).
The main road 4 leads on the bank around the Lopper from Alpnachstad to Hergiswil NW . The A2 motorway was initially built along the north bank. As a result of the unstable slopes, it was decided in the mid-1980s to relocate the motorway into the interior of the mountain in order to prevent this “ bottleneck ” from being interrupted . The Kirchenwald tunnel was opened in 2006 . The Loppertunnel , which opened in 1984 and leaves at the Lopper junction , is the beginning of the A8 motorway towards Sarnen , Brünigpass and Interlaken . Since December 2008 there has been a new connecting tunnel from the Kirchenwald tunnel to the Loppertunnel, so that traffic coming from Stans can also branch off onto the A8, which makes detours unnecessary. The new junction joins the A8 next to the existing south portal of the Loppertunnel before Alpnachstad.
The Luzern-Stans-Engelberg-Bahn runs through a 1743 meter long tunnel on the northern slope of the Lopper. The Brünigbahn crosses the mountain in a tunnel 1186 meters long.
However, the cantonal road between Hergiswil and Stansstad continues along the endangered northern slope, protected by a gallery . On October 12, 2009, a rock fall broke the road. It had to remain closed during the renovation work on the slope. The connection between Hergiswil and Stansstad was maintained between March 2010 and May 2011 via a single-lane pontoon bridge . This 500 meter long bridge was unique in Europe.
Others
On October 23, 2013 crashed F / A-18 of the Swiss Air Force from the south wall of loppers. Both inmates were killed. According to the final report of the military examining magistrate, the crash was due to a misjudgment by the pilot. In addition, a reversal maneuver that was not carried out with the utmost consequence is held responsible for the accident.
