The Sofia ring road (Bulgarian: Софийски околовръстен път, Sofiyski okolovrasten pat) is an important thoroughfare surrounding Sofia, the capital of Bulgaria. The ring road is around 60 km long and has recently been upgraded on several sections, with plans to further improve it on the remaining sections.
The Sofia ring road is divided into four sections (arcs), at south, north, west and east. A major part of southern arc has been significantly upgraded in several stages between 2007 and 2012, providing now a conflict-free connection between the Boyana and the Mladost IV junctions. The next planned upgrade on the southern section will be between the Buxton district and the Lyulin motorway (A6), which may begin after 2013. The segment between Mladost and Tsarigradsko shose blvd / Trakia motorway (A1) interchange has conceptual design since 2015, with a proposal to be upgraded with an EIB loan.
The eastern arc, which lies between the Trakia motorway (A1) and the Hemus motorway (A2), is grade-separated and provides three traffic lanes and a hard shoulder in each direction. Though, it's not signed as a motorway and a 90 km/h (56 mph) speed limit applies.
In the northern part of city, the Northern Speed Tangent connects the Mramor village with the Hemus motorway. It is a controlled-access highway, designed to carry the transit traffic and supersedes the existing northern arc. It was tendered in 2012, the construction works began in 2015. and it was inaugurated in April 2016.
