Its first line, the construction of which was completed in April 2018, is intended for the Turkish market, the second one – for deliveries to countries of South and Southeast Europe.

Bulgaria&#39;s state gas operator Bulgartransgaz has signed a EUR 1.1 billion (US$1.2 billion) contract with the consortium led by Saudi Arabia&#39;s Arkad Engineering to build a TurkStream pipeline extension to supply natural gas from Russia to parts of Europe bypassing Ukraine. The contract envisages laying a 474-kilometer (296-mile) pipeline that would extend from Bulgaria&#39;s southern border with Turkey to its western border with Serbia. The pipeline is expected to deliver gas to Serbia, Hungary and Austria as an offshoot of Gazprom&#39;s TurkStream pipeline.
