Fourth metro would link north and south Rome.

Rome city council is reviewing plans to revive Metro D, Rome's fourth subway, according to the capital's mobility commission.

First announced in 2005, the Metro D plan was dropped in 2011, for financial reasons, under the administration of former mayor Gianni Alemanno.

The head of the mobility commission, Enrico Stefàno, said that the city must now choose between restarting the stalled process or beginning again from scratch, together with updated economic assessments. Stefàno made no reference to estimated costs.

Metro D would link EUR in the south of the city with Montesacro in the north, running for 20 km through 22 stations.

According to the original 2005 plan, Metro D's central section would encompass 10 new stations (Fermi, Trastevere, Nievo, Mastai/Belli, S. Silvestro, Fiume/Boncompagni, Buenos Aires, Verbano Nemorense, Acilia Vescovio and Prati Fiscali) as well as linking to the A line at Spagna and the C line at the proposed Venezia station.

Currently three central metro stations on the A line are closed due to malfunctioning escalators.
