It is 13 km long and has 6–10 traffic lanes with a rapid tram line on the median of the boulevard.
The construction started in 1980, the first part was completed in 1984 with the new Árpád Bridge (2×3 traffic lanes and 2 tram tracks).
To make way for the urban highway, the majority of the small houses on the planned route were demolished.
The last section was finished in 2000, Rákóczi Bridge was built in 1995.
Nowadays the boulevard doesn't have a uniform facade: there are socialist block of flats and modern high-rise office buildings along Hungária körgyűrű.
