Silvaplana bypass
The Silvaplana bypass ( Rhaeto-Romanic in the idiom Puter sviamaint da Silvaplauna ) has bypassed the town of Silvaplana in the Upper Engadin since June 2018. The Silvaplana municipality took on an advance financing of this section of the Julierpassstrasse in order to ensure that construction began in summer 2010 and not in 2012, as originally provided by the civil engineering department of the Canton of Graubünden .
The first considerations to relieve the town center of Silvaplana from motorized traffic were made as early as 1929. Three bypass projects have been worked out since 1950, but were not implemented mainly due to financing issues relating to the distribution key between the federal government, canton and municipality and due to residents' speeches.
The total length of the bypass is 1470 meters. The heart of the route is a 750-meter-long tunnel, which has to meet high safety requirements due to a longitudinal incline of 8.5 percent. Five escape exits lead through tunnels that run parallel to the road.
The entrance portal is in the last hairpin bend near Pignia Nord before the town center, the exit portal at Piz Sura . From there the bypass leads to a roundabout at Lej da Champfèr , where it joins the Engadinerstrasse .
The old Julier Pass road will be preserved for non-motorized traffic and will be used as a replacement route in emergencies.
