OP Transport and development

Operational Programme "Transport"
Sofia Metro Extension Project 

 

 

Since 2009 after inclusion in OP "Transport", predominantly by funding from the European Regional Development Fund (ERDF) and Cohesion Fund (CF) of the European Union with a local co-financing, has started the implementation of large-scale Sofia Metro Extension Project. It includes the construction of Line 2 and a significant extension of Line 1 of the Sofia metro. It is divided into three stages. The first two stages were completed on 31.08.2012.
 

The total length of sections amounts to 13 km with 13 stations. By this the length of metro lines after the completion of these stages has increased to 31 km with 27 stations and approximate number of passengers carried more than 300 thousand/daily. In 2013 has been launched the third stage of the project.



 
 

STAGE І: CENTRAL SECTION OF LINE 2 "NADEZHDA OVEPASS - SV.NEDELYA QUARE - NDK - CHERNI VRAH BLVD."

(CONSTRUCTION 2009 - ІХ.2012)

 

 
The first stage of the Sofia Metro Extension Project, included in OP "Transport" includes the route: "Nadezhda Overpass - Central Railway Station - Sv. Nedelya Sq. - NDK - Cherni Vrah blvd." 6.4 km long with 7 stations
 

The financing of this stage is carried out under Priority Axis 3 "Improvement of intermodality in passengers and freight transportation" of OP "Transport" by the ERDF. The grant by the ERDF amounts to 157 million Euros, with co-financing by the Sofia Municipality of 25% of the value of the stage. Application Form for funding together with the Cost-Benefit Analysis was approved by the European Commission in 2009. The final completion of the stage, after its adoption by the State Acceptance Commission at the end of August 2012, has took place in October 2012, as this stage was completed both physically and financially.

Construction of this section has began in the spring of 2009 and has ended on 31.VІІІ.2012. It included construction of structures of tunnels and metro stations, architectural design of the stations, reconstruction and restoration of the affected urban infrastructure engineering, supply and installation of equipment of the management and operation systems of the metro, including 3 systems for transport automation and safety, 3 dispatch control systems, communication systems, sanitary-technical systems, etc. -  i.e. complete engineering.

There were applied complex design and technological solutions, some of which are unique, due to the complex geological and hydrogeological conditions along the route and the passage under existing facilities, including under existing tunnels of Line 1, under subways, under Lion's Bridge, due to the requirement not to completely stop the traffic around the construction sites, as well as to preserve the archaeological finds in the center of the city.


 

Tunnels in the section "Nadezhda Overpass - Patriarh Evtimiy blvd." with a length of 3.8 km and 4 stations are double-track tunnels with an inner diameter of 8.43 m, completed by aspecially produced for the conditions of the Sofia Metro tunnel boring machine (sealed hydro-shield) by the German company "Herrenknecht".

STAGE ІІ: LOT 1 – SECTION OF LINE 2 "OBELYA RD - NADEZHDA RD - NAZHDA OVERPASS" AND LOT 2 - SECTION FROM LIKE 1 "MLADOST 1 (MS 13) - TSARIGRADSKO SHOSE BLVD. WITH AN UNDERGROUND PARKING LOT"

(CONSTRUCTION 2009 - ІХ.2012)

Financing of Stage II which is included in the OP "Transport" was carried out by the grant from the Cohesion Fund - 200 million Euros and 20% local co-financing by the Sofia Municipality provided by a loan from the EIB.

The route of "Obelya RD - Nadezhda RD - Nadezhda Overpass" was defined as Lot 1 of Stage II of the Sofia Metro Extension Project due to the necessity to be provided a connection of the area funded by the OP "Transport" (Stage I), with the depot in Obelya area where the trains are being serviced and repaired, and also to provide a fast and efficient transport for Nadezhda, Svoboda, Tolstoy and Vrabnitsa residential districts with a total population of more than 120 thousand people.

In this view and the need for a parallel construction of this section together with the section of the route included in Stage I of the Project, Sofia Municipality has provided partial advanced funding for this and in 2010 has started the construction of the section "Obelya RD - Nadezhda RD - Nadezhda Overpass" (Fig. 1) with a length of 4.16 km, out of which 1.3 kilometers were opened - on overbridge and 2.86 kilometers underground. Three metro stations are underground, and the final is on an overbridge.

To satisfy the increased demand for efficient and safe transport of the population of the territories of the large residential discricts of Mladost and Duzhba located in the southeastern part of the city, in 2009 has began the construction of a section "Mladost I RD - Mladost III RD - Tsarigradsko Shose blvd.", which is part of the section from Mladost to Sofia Airport (Fig. 1) included in the OP "Transport" 2007-2013. It has a length of 2.5 km and 2 underground stations and represents Lot 2 of Stage II from the Project.
