Bulgaria: Construction of Balkans' Longest Tunnel between Sofia and Burgas Starts in Bulgaria

Bulgaria has begun construction of the longest tunnel in the Balkans, as part of the railway between Sofia and the Bulgarian Black Sea city of Bourgas.

The tunnel is located about 30 kilometres from Sofia in a mountainous area and is 6.8 kilometres long, making it twice as long as Bulgaria’s current longest tunnel, in Koznitsa.

It is part of a major project to modernise the Trakia railway from Sofia to Bourgas, which has been under construction for 15 years. The hopes are that the project will be completed by 2030. The funds are provided by the EU Operational Programme, Transport.

The contract for the construction of the tunnel is worth €300 million, and construction is being carried out by Turkish companies involved in the construction of the new airport in Istanbul. The Turkish company Cengiz has experience in Bulgaria with the construction of the 19-kilometre Lyulin highway, which is part of the Struma highway and connects Bulgaria and Greece.

Turkish companies will rely on their workers who have experience with such sites in Turkey to dig the new tunnel. Bulgaria has issued work visas to about 230 Turkish engineers, giving them 72 months to complete the project.
