Rome Metro Line C extension: €776m deal for Section T1

Rome Metro Line C extension plans have moved forward again after Roma Metropolitane — on behalf of the city council — awarded a €776m design and build contract for Section T1.

This is reported by the railway transport news portal Railway Supply.

The work has been assigned to the Metro C consortium led by Webuild and including Vianini Lavori, as reported by International Railway Journal. Webuild has said its share of the contract is worth €268m, according to a Webuild statement.

Section T1 Clodio/Mazzini to Farnesina

Section T1 will extend the line from Clodio/Mazzini to Farnesina in northeast Rome. Webuild says the extension is being delivered in an integrated manner with the 4 km Section T2 between Venezia and Clodio/Mazzini, so mechanised excavation can continue from Farnesina to Venezia without splitting the programme into separate chunks.

Section T2 Venezia to Clodio/Mazzini and the River Tiber crossing

For Section T2, design work is already under way under a €2bn design and build contract awarded to the Metro C consortium last year. This section includes the first metro crossing under the River Tiber.

Section T3 progress and newly opened stations

At the western end of the 3 km Section T3 running from San Giovanini, work to build Venezia station is still ongoing. A 2.4 km section has already entered service, and the two intermediate stations — Porta Metronia and Colosseo/Fori Imperiali — were officially opened on December 16, a step also covered by Railway Supply.

Colosseo/Fori Imperiali sits between the Colosseum and the Basilica of Maxentius. It reaches a maximum depth of 32 m, has four underground levels, and provides a direct connection to Colosseo station on Line B. Porta Metronia, located in Piazzale Ipponio beside the Aurelian Walls, has five underground levels reaching a maximum depth of 30 m below street level.

Webuild describes the Rome Metro Line C extension as part of one of the most complex infrastructure projects ever undertaken in the city. The Colosseo/Fori Imperiali and Porta Metronia builds used the top-down method developed specifically for stations in Rome’s historic centre, with intermediate slabs installed progressively as excavation proceeds from top to bottom. This approach is intended to help maintain structural stability while allowing archaeological investigation to continue as construction work proceeds.

When completed, Line C will run for 29 km from Monte Compatri/Pantano in the eastern suburbs to Farnesina and serve 31 stations in total. At present, 24 stations are open to traffic between Monte Compatri/Pantano and Colosseo/Fori Imperiali.

“We are building a transport system that improves people’s lives, saves time lost in traffic and ensures cleaner air for future generations,” says Webuild chief executive Pietro Salini.
