Struma Motorway, Bulgaria


Struma Motorway is a major road infrastructure project located in the Yugozapaden region of South West Bulgaria. Running between capital city Sofia and Kulata at the Bulgaria-Greece border, the total length of the motorway will be 173.8km.

Two sections of the motorway were completed in 2011, the 19km Lyulin stretch that connects the Sofia ring road with the junction of Daskalovo near Pernik and a 22km section between Daskalovo and Dolna Dikanya to the south of Sofia.

The remaining 132.8km of the Struma motorway project has been divided into four sections. Construction of sections 1 and 4 started in 2011 and 2012 respectively. The construction contract for section 2 was awarded in February 2013.

Section 3, which is the most complex section of the project, is currently in a preliminary design phase, with the construction planned for after 2014.
