How much does Santiago Metro Line 8 cost?
Santiago Metro Line 8 is a planned 19-km underground line with 14 new stations linking Providencia with Puente Alto through Ñuñoa, Macul, Peñalolén and La Florida, to be built with the New Austrian Tunnelling Method and expected to cut the trip between the ends from about 57 to 23 minutes.
