Tsarigradsko shose (Bulgarian: Цариградско шосе, Tsarigradsko shosé, literally meaning Tsarigrad (Istanbul) Chaussée (Road)) is the largest boulevard in the capital of Bulgaria, Sofia. It begins from Orlov Most (Eagle's Bridge), before which it is called Tsar Osvoboditel Boulevard, and in the end becomes part of the Trakiya motorway (A1). It runs from the north-west to the south-east. The maximum allowed speed on Tsarigradsko shose is 80 km/h between Orlov Most and Gorublyane neighbourhood. To the south the boulevard borders with Sofia's largest park, the Borisova Gradina, which hosts the National Stadium Vasil Levski and Bulgarian Army Stadium. A number of departments of the Bulgarian Academy of Sciences are situated along the road in the area of the Fourth Kilometer Square, as well as the Ministry of Foreign Affairs, the Polygraphic plant and several hotels including the emblematic Pliska Hotel. In the outskirts of the city there are a lot of hypermarkets and office buildings constructed along the boulevard.
