A1 motorway, motorway in Switzerland
The A1 is Switzerland's main transportation corridor, spanning about 345 kilometers from Geneva in the west to St. Gallen in the east. It crosses through diverse cantons and terrain, functioning as the country's central artery for both passenger and freight traffic.
Construction of the A1 spanned from the 1960s to the 1980s, built in stages to serve Switzerland's growing population and commerce. This two-decade project marked a turning point in modernizing the country's transportation network and connecting its major economic centers.
Rest areas, service stations, and exits are distributed regularly along the route, providing convenient access to towns and facilities. Peak travel periods, especially on weekends and during holidays, often experience significant congestion that drivers should plan for.
