History

This interchange was built in 1960s as part of infrastructure development for 1962 Asian Games.[1] David Gee Cheng, the Indonesian Deputy Minister for City Planning and Construction, and Sutami, the state minister for construction assessment, presented their proposals to President Sukarno. Afterwards, Cheng and Sutami argued with each other about their proposals, with Sukarno observing them. Sukarno later chose Sutami's proposal as a blueprint for the interchange.[2] It was named after Semanggi (cloverleaf) by Sukarno. It was originally designed as one long continuous bridge with cloverleaf interchange. This design symbolized the unification of the territory of the city, as well as a symbol of Indonesian national unity. The clover shape was inspired by Irish mythology: the four-leaf clover which is widely considered as a good luck charm. Before the development of Karet area, a swath of swamp full of clovers used to exist around it.[3]

In 1987, the interchange was modified with the construction of two additional bridges alongside the original Gatot Subroto Road bridge. The modification was done to make way for the construction of Jakarta Inner Ring Road, which would use the original bridge structure. As the result, the 270-degree loops was completely rebuilt with box tunnels underneath instead of being an elevated structure like before.[4] The modified Semanggi interchange was opened by President Suharto on 10 November 1989.[5]

In 2015, then Governor of Jakarta, Basuki Tjahaja Purnama revealed a plan to build two elevated roads around the Semanggi cloverleaf to reduce traffic congestion in the area. This new bridge stretch allows road users to drive from Ratu Plaza in South Jakarta to Cawang in East Jakarta and from Grogol in West Jakarta to Kebayoran Baru in South Jakarta.[6][7] The new elevated road is built above the existing Semanggi intersection in front of the well-known Semanggi shopping mall in South Jakarta. The West-South ramp is 769 meters long (between 6 and 11 meters above ground level). The other ramp is approximately 826 meters long with a height of up to 11.5 meters. It was opened to traffic on 28 July 2017.[8]
