Connecting East Coast Parkway (ECP) in the south and Tampines Expressway (TPE) in the north-east, the six-lane (2x3) expressway extends for twelve kilometres, with approximately 8.5 kilometres (5.3 mi) of main cut and cover tunnels[4] running some 10 kilometres underground when fully completed. Built at a cost of approximately S$1.8 billion (USD$1 billion), it is the longest subterranean road tunnel in Southeast Asia. The KPE is also believed to be the world's sixth longest underground road project at its time under construction.[5] In all, the dual-carriageway expressway with three lanes in each direction will have eight interchanges, eleven on-ramps, and twelve off-ramps. The south end of the KPE also connects directly to the Marina Coastal Expressway which opened on 29 December 2013.
The Land Transport Authority (LTA) has awarded a contract for the expansion of the KPE/TPE interchange at the north end of the expressway and construction of a new road connection to Punggol Central, providing a new and more direct link to and from the KPE and TPE, and alleviating the traffic congestion of the TPE between the current KPE ramps and Punggol ramps. The work would involves the design and construction of roads, three new vehicular bridges crossing Sungei Serangoon and Sungei Blukar, a new flyover across TPE and other associated ramps. Construction works commenced in the second quarter of 2015.
