A13 (Switzerland)

The A13 is a motorway, at times a motorroad (German: Autostrasse, or motorroad, alternatively an express route), which runs from St. Margrethen in northeastern Switzerland through to Bellinzona in south Switzerland.The A13 started life as a road which was mainly motorroad, from the foggy beginnings at St. Margrethen through to Haag, near Liechtenstein. The motorway would begin from Haag through Reichenau. Then it would be a motorroad again until after Mesocco, until Roverdo. The final kilometres linking it to the A2 motorway would be a motorroad. Today, the section from St. Margrethen through Haag has been thoroughly converted to a motorway. Due to the tough terrain, the transformation of the Graubünden section into a full motorway would be difficult.
