Construction of the largest expansion in Stockholm public transport since the Blue Line was built in the 70s began with a ceremonial starting blast in a rock cavern in Barkarby.  The metro’s Blue Line is to be extended from Akalla to Barkaby, and from Kungstradgarden to Nacka in the southern suburbs. A brand-new Yellow Line will be built from Odenplan to Arenastaden and eventually a new line will also be built from Fridhemsplan to Alvsjo.
