It marks the triple-point boundary of the planning areas of Kallang, Geylang and Toa Payoh.
A flyover to cater to traffic heading towards the Central Expressway (CTE) was also included in the project.
There has also been major traffic congestion at the at-grade road interchange, with a possible gridlock in a few years time.
To ease the traffic flow, the Land Transport Authority announced in 2007 that the interchange will go through an upgrading project.
