Piraeus

Piraeus

The Metro Line 3 Extension to Piraeus, which is in an advanced stage of construction, includes a 7.6 km long tunnel and 6 new modern stations (Aghia Varvara, Korydallos, Nikaia, Maniatika, Piraeus and Dimotiko Theatro) as well as seven ventilation intershafts.

This is an investment rising to 730,000,000 euros in areas of the Municipality of Piraeus and other neighboring Municipalities (Nikaia, Korydallos, Aghia Varvara) , all of which are currently faced with acute traffic problems and low accessibility by the public transport modes.

On July 6, 2020, the first 3 stations of Aghia Varvara, Korydallos and Nikaia were commissioned. It is worth mentioning that these stations have been designed by Attiko Metro S.A. in a manner placing emphasis on bioclimatic characteristics and safe passenger trips in the Metro network

Upon commissioning of the first three stations of the Piraeus extension, the daily ridership on the entire network is expected to be increased by 63,000 passengers; at the same time, a modern Metro line shall be made available to the residents of the aforementioned three Municipalities.

The commissioning of the first 3 stations approximately 2 years earlier than the completion of the overall extension of the Metro Line 3 brings about significant socio-economic and other benefits, such the reduced carbon footprint and private vehicle circulation (less 60 tons of CO2 and 11,000 cars per day).

The entire Line 3 Extension is expected to be commissioned in summer 2022.

With the completion of the project and the commissioning of Maniatika, Piraeus and Dimotiko Theatro stations, the total ridership figure on the Metro network is foreseen be 132,000 passengers / day, thus reducing the circulation of private vehicles by 23,000 cars per day and the carbon dioxide emissions by 120 tons per day. It is pointed out that the distance from Piraeus Port to the Athens International Airport shall be covered by the Metro in just 55 minutes.

It is important to emphasize that with the completion of the project, a major Transport Center is foreseen to be developed at Piraeus Station, which shall functionally intergrade two Metro lines (Lines 1 and 3), the actual Port, the Suburban Railway and the Tramway Extension to Piraeus (5.4 km long single line and 12 stops), facilitating thus intermodal transfers.

In addition, the resulting connection between the Port of Piraeus and the Athens International Airport via the Metro Line 3, will foster growth in the greater area of Athens and Piraeus, with substantial benefits to the National Economy in general.
