history
The connection from Basel via Lake Zurich , Lake Walen and the Graubündner Passes to Milan was the most important Alpine transit route from the early Middle Ages to the 18th century and much more important than the Gotthard Pass .
Aargau
In 1773 the Bernese council approved the construction of a new Bözbergstrasse after Austria had already expanded its road through the Fricktal in 1754. The Piedmontese engineer Antonio Maria Mirani supervised the construction work, which began in 1777. On December 10, 1779, one year after Mirani’s death, Bözbergstrasse was open to traffic.
St. Gallen
Up until the 19th century there was no continuous road along the Walensee. The state road «1. Class », which was established by the canton of St. Gallen in 1834 , ended in Walenstadt on the shores of Lake Walen. It was not until long after the Rapperswil – Sargans railway line opened in 1859 that the state road on the south bank of the Walensee was also expanded around 1890.
Grisons
The canton of Graubünden also had the Obere Strasse from Chur via the Julier and Maloja passes to Castasegna on the Italian border expanded as a commercial route from 1820–1828 . After a devastating flood on August 24, 1834, which destroyed the 70-kilometer-long Untere Strasse in the Hinterrheintal, the entire Alpine transit ran via this alternative route, which was expanded to a five-meter-wide Commercialstrasse at a cost of 1.24 million francs. After the Gotthard Railway opened , significantly fewer goods were transported over the pass roads.
The section between Tiefencastel and Silvaplana has belonged to the federal government since 2020. Since then it has been part of the National Road 29.
