Semanggi intersection comprises the shape of a four-leaved cloverleaf (Semanggi in Indonesian). Two main road of the city Gatot Subroto Road and Sudirman Road intersects at the Semanggi cloverleaf bridge. This is a landmark and an important arterial road in the Golden Triangle of Jakarta, an area of Jakarta’s business district.

This interchange was built in 1960s as part of infrastructure development for 1962 Asian Games. It was named as Semanggi (cloverleaf) by Soekarno with one bridge and four leaves symbolizing the unification of the territory of the city, as well as a symbol of Indonesian national unity. There is a myth in Ireland, that the four-leaf clover is a lucky clover that is believed to bring good luck. It is said that the area of Karet in Jakarta, where the interchange is located was the swamp that grew Semanggi (clover) plants. In 2015, Governor of Jakarta revealed a plan to build two elevated roads around the Semanggi cloverleaf in an attempt to reduce traffic congestion in the area, from Ratu Plaza in South Jakarta to Cawang in East Jakarta and from Grogol in West Jakarta to Kebayoran Baru in South Jakarta.

The circular elevated roads or flyover around the interchange is named as Simpang Susun Semanggi. The flyover is built above the existing Semanggi intersection in front of the well-known Semanggi shopping mall in South Jakarta. The elevated roads will cater to vehicles traveling from Grogol, West Jakarta to Senayan, South Jakarta, and from Sudirman (Central/South Jakarta) to Cawang, East Jakarta.
