National roads
National roads form the backbone of the Swiss road network. They connect Switzerland to the European road network, link different parts of the country together and absorb a significant proportion of the traffic in towns and urban areas.
Construction sites and projects
The Federal Roads Office (FEDRO) is responsible for the construction, maintenance and operation of the Swiss motorway network. On this page you will find information and explanations about the most important construction sites and projects on the freeways.
