Under-planning Santiago Metro line
Line 7 is a new rapid transit line due to open on the Santiago Metro, in 2027. Intended to relieve the busy Line 1, the Line 7 will start in Renca in the northwest, passing through the city center, before ending in the borders of Las Condes and Vitacura in the northeast. Expected to be finished by 2028, it will add 19 new stations and 24.8 km (15.4 mi) of track to the system. Its distinctive color on the network line map is gray. Cost of construction has been set at $2.5 billion USD.[2]
