Tsarigradsko shose

Tsarigradsko shose (Bulgarian: Цариградско шосе, Tsarigradsko shosė, literally meaning Tsarigrad 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 Tsarigrad Road 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 Forth 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.

The boulevard bears the old Bulgarian name of the city of Istanbul (medieval Constantinople), Tsarigrad, as it leads southeastwards out of the city, towards Plovdiv and Istanbul.
