Barcelona's underground faces an important challenge for the future: to take on in a decade one of the most important expansions of the network in its history, as well as the renewal of its oldest mobile material. This challenge is based on the written commitment by all the competent institutions in the Infrastructures Managing Plan (Plan Director de Infraestructuras), (PDI) for the period 2001-2010; ultimately agreed by the Board of Directors of the Metropolitan Transport Authority (Consejo de Administración de la Autoritat del Transport Metropolità). The dates for its building and the budget needed to make it a reality are specified in the said plan.

Stretching all the lines

The present 5 underground lines will be stretched in some of their extremes. Their specific expansions will be:

Prolongation L1: Fondo - Badalona i Feixa Llarga - El Prat.
Prolongation L2: Pep Ventura - Morera and Sant Antoni - Foc Cisell.
Conversion to L2 of the present stretch of L-4 La Pau-Pep Ventura.
Prolongation L3: Canyelles - Trinitat Nova.
Prolongation L4: La Pau - Sagrera i Trinitat Nova - Can Cuiàs.
Prolongation L5: Horta - Vall d'Hebron
