Line A () is a line on the Lyon Metro that runs between Perrache and Vaulx-en-VelinâÂÂLa Soie. It was constructed using the cut-and-cover method, and went into service on 2 May 1978. It, together with Line B, were the inaugural lines of the Lyon Metro. An extension of Line A from Laurent BonnevayâÂÂAstroballe to Vaulx-en-VelinâÂÂLa Soie opened in 2007. The line currently serves 14 stations, and is long. Line A trains run on tires rather than steel wheels; it is a rubber-tired metro line.
Line A was extended eastwards from Laurent BonnevayâÂÂAstroballe to Vaulx-en-VelinâÂÂLa Soie (1 station) to provide connection with the new express tram line to LyonâÂÂSaint-Exupéry Airport, called Rhônexpress as well as tram line T3. This extension opened on 2 October 2007 and cost â¬53 million.
