The section on former Soviet territory (Almetievsk – Kuibyshev – Unecha – Mozyr – Brest, with the Mozyr – Brody – Uzhgorod branch line) is 3,004 km long. This part of the pipeline was designed not only to deliver oil to the European Comecon members but also to ensure supplies to oil processing plants in the western regions of Russia and the export of oil to other countries via the Baltic port of Ventspils.
Crossing the former Czechoslovak territory, from Uzhgorog – Sagi – Bratislava, Sagi – Hungarian state border, Sagi – Gnevitse, is 836 km long. The section on Polish territory stretches from the former Soviet border – Plock – former GDR border and is 675 km long. Approximately 27 km is located on former GDR territory from the state border to the town of Schwedt, and
123 km on Hungarian territory from the state border to Sashalombat.
The pipeline cost approximately 400 million roubles ($US12.7 million) to build – as much as 730,000 tonnes of pipe were laid along the route and more than
15 million cubic metres of earth were moved. The pipeline crossed 400 water barriers, including 45 major rivers, and more than 200 railways and highways.
Oil from the pipeline first reached Czechoslovakia and Poland at the beginning of 1962, and Hungary and the GDR in 1963.
Over its lifetime, the Druzhba Pipeline system has provided conditions for a reliable and uninterrupted supply of Russian oil.
An important economic advantage has been the considerable reduction in transport costs – previously much of the oil was carried by rail, but with the introduction of the pipeline, transport costs fell to an average of 20–25 per cent of rail carriage figures.
