This very costly project was progressively abandoned: first, in 1984, by shortening the line.
Later, in 1996, a new plan was devised for the city's public transport infrastructures.
In 2001 yet another plan (PDI) was put forward, discarding the line, and proposing other transport projects instead.
Plaça de Francesc Macià was in contemporaneous plans an important transport hub with other (later discontinued) projected metro lines.
As of 2009, both the 22@ and Francesc Macià areas have no metro service, but the projected extension of line L8 and the construction of L9 and L10 follow it very closely.
