The initial invitation to tender for Line 2 extension to Helliniko initially foresaw the construction of a bridge along the central island of Vouliagmenis Avenue, which would create significant sound and visual disturbance. Following a decision made by the Ministry of Infrastructures, Transport and Networks, the said tender procedure was annulled and ATTIKO METRO S.A. called for a new tender based on which the entire Line would be constructed below surface. A thorough examination of the construction method proved that the Line could be underground with a slight difference in the budget and the time needed for the construction of the project.
The contract related to the underground extension of Metro Line 2 to ELLINIKO was signed on March 8th 2006. The extension will be 5,5 km long in total and includes 4 new stations: ILIOUPOLI, ALIMOS, ARGYROUPOLI and HELLINIKO, as well as an underground area for the stabling of eight trains to serve the needs of the extension.
All new stations are 110m long, consist in three levels and there are entrances/exits on either side of Vouliagmenis Avenue. The tunnel has been bored using a TÂÌ-ÅÑÂ boring machine, whose cutter head will be 9,5m in diameter. The stations, the ventilation and E/M shafts, as well as the train stabling area were constructed using the C/C method.
This Line extension provides transportation services to the wider area along the axis of Vouliagmenis Avenue, i.e. the areas of the municipalities of Aghios Dimitrios, Ilioupoli, Argyroupoli, Alimos and Elliniko. In particular, with the addition of the said extension to the Metro network, the daily ridership is anticipated to be increased by 80,000 passengers. On the contrary, daily trips by car will be reduced by 50,000.
In addition, the restructuring and the extension of the local urban transport system, with the development of Transfer Stations to and from the Bus Lines, as well as the creation of future Car Parks at the New Stations is anticipated to serve the southern municipalities, such as the ones of Glyfada, Voula etc. It is worth mentioning that the distance from HELLINIKO Station to the city centre (SYNTAGMA Station) will be covered in only 14 minutes, while by car in rush hour it takes more than 45 minutes!
