Kallang & Paya Lebar Expressway

The Kallang and Paya Lebar Expressway (KPE), Southeast Asia’s longest underground expressway, is one of the most complex and technologically ambitious engineering projects Singapore has ever undertaken.

Stretching from the East Coast Parkway (ECP) in the south to the Tampines Expressway (TPE) in Northeast to serve the growing residential, commercial and industrial needs. KPE total length is 12 km with approximately 8.5 km of main tunnels, eight interchange with four on/off-slip roads, at-grade, and depressed roads.

The tunnel structure is dual 3-lane twin-cell box structure, separated by a common wall. Slip road tunnels and the associated depressed carriageway will be design as single box tunnels. The design also includes a multi-span bridge crossing the Geylang river. The bridge is supported by piers sitting on top of the tunnel box beneath the riverbed.

Phase 1, the section that extents from the ECP to the PIE, opens to the public on 26 October 2007. SCAE consultancy works in phase 1 were from ECP to Nicoll Highway, total length of 1.5 km.
