Contractor Seli continues to make significant progress on Phase 3 of the Line 5 metro extension in Milan, Italy.

Double breakthrough for Seli EPBMs on Milan Metro Line 5

The Italian TBM manufacturer and tunnel services company reports breakthroughs for both its machines at Cenisio Station. The machines are excavating 1,940m-long twin-tube tunnels of 6.79m and 6.76m diameters, with progress currently recorded at 1,118m and 756m respectively.
Internal diameter of the 30cm thick precast concrete lining is 5.8m, with each ring made up of six segments and a key.
Construction of the US$1.2 billion 6.7km Garibaldi-San Siro LRT section of Line 5 is being carried out by a JV comprising Astaldi/Ansaldo Breda/ATM/Alstrom. Excavation of the eastbound drive between Monumentale Station and Tre Torri began in August last year (2012) and is scheduled for completion in May 2014.

The 5km-long eastbound drives from San Siro through to Tre Torre will be completed with two more TBMs, with the total 10-station extension expected to be complete in time for EXPO 2015.
The 4.1km Phase 1 Bignami-Zara section, including seven stations, was completed earlier this year, with full service beginning in February. Unlike the rest of the alignment this is a double track tunnel, excavation of which was completed in 2011.
The 1.9km Phase 2 construction between Zara and Garibaldi, via a station at Isola, is expected to open by the end of this year (2013) and will add connections with Line 2 at Garibaldi and Line 3 at Zara. Once complete the whole 12km extension will feature driverless trains.
A feasibility study for a further 6.3km Line 5 extension between Bignami and Monza has been completed, while 9.7km and 14.8km extensions are planned for Lines 2 and 3 respectively.
