Pushing ahead with Milan metro Line 5 26 Mar 2013
- Contractor Seli continues to make significant progress on Phase 3 of the Line 5 metro extension in Milan, Italy.
- 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.
Milan Metro Line 5 due for full completion in 2015
- 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.
