The Kallang–Paya Lebar Expressway (Abbreviation: KPE; Template:Zh; Template:Lang-ms; Template:Lang-ta) is the third newest of Singapore's network of expressways. The southern section of the expressway opened first, on 26 October 2007,[1] with the remaining section fully opened on 20 September 2008.[2][3]

Connecting the East Coast Parkway in the South and the Tampines Expressway in the north-east, the 6 lane (2x3) expressway extends twelve kilometres, with approximately Template:Convert of main cut and cover underground tunnels[4] running some 10 kilometres underground when fully completed. Built at a cost of approximately S$1.8 billion (US$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 KPE also connects to the Marina Coastal Expressway which recently opened on December 29, 2013.

HistoryEdit

Construction on the expressway started in the year 2001, and was fully completed in 2008. On 23 June 2007, the northern end of the expressway between Tampines Road from the new Defu Flyover and the Tampines Expressway was opened to traffic, and was temporarily named Tampines Service Road.[6] Tampines Road will therefore no longer connect with the Tampines Expressway at the Tampines Flyover. The Defu Flyover along Tampines Road, along with the traffic signals, were commissioned on the same day from 1000 hours.[7]

On 27 July 2007, the LTA announced the opening of the southern ECP-PIE section of the expressway (Phase 1) to traffic on 26 October 2007.[8] The entire expressway opened to traffic on 20 September 2008 by Prime Minister Lee Hsien Loong.[2][3]

From the 12 August 2008 to 18 August 2008, the KPE is closed. This is to facilitate the smooth transition for the full expressway, including thorough checks of the tunnel. The transition also involves integrating key operation systems of the existing stretch of KPE with the new and unopened stretch of the expressway. Some of these systems include ventilation control, fire protection and lighting control. Comprehensive tests will be conducted on the integrated systems to ensure that they are working well and operationally ready when the expressway opens. The operations control centre will therefore be shifted to Airport Road from Sims Way.

RouteEdit

The Kallang Section of the expressway starts from an interchange with the East Coast Parkway near the fourteen-kilometre mark of the ECP in a northward direction, goes underground below the Geylang River, cuts across the Kallang Sports Complex to the west of the National Stadium, comes to an interchange at the Mountbatten Road/Nicoll Highway/Guillemard Road junction, crosses the East West MRT Line, before ending with an interchange with the Pan Island Expressway at the thirteen-kilometre mark of the latter.

The Paya Lebar Section continues from where the Kallang Section leaves off beneath the Kallang River and Pelton Canal past MacPherson Estate, comes to an interchange with Paya Lebar Road, Upper Paya Lebar Road, MacPherson Road and Airport Road, crosses over the Circle MRT Line which was under construction at the same time as the expressway, and continues for almost three and a half kilometres underground beneath Airport Road and the Paya Lebar Airbase, emerges at ground level near Defu Lane 3, goes on an elevated interchange over Tampines Road. It will meet Buangkok East Drive at an interchange[9] before continuing towards the existing Tampines Flyover to meet with Tampines Expressway.

On 27 July 2007, the LTA announced an extension of the KPE from East Coast Parkway to the Ayer Rajah Expressway via Marina South. The stretch will be named Marina Coastal Expressway (MCE). The Marina Coastal Expressway officially opened on 29 December 2013.

Public education and congestion managementEdit

In 2006, the Land Transport Authority (LTA) engaged an advertising agency to embark on a public education programme, to inform and educate the public on the proper way to use the KPE — the first time it has done so for a road project. British firm Bartle Bogle Hegarty (BBH) has been appointed to publicise safety messages needed to prepare users for the KPE. BBH, which in turn appointed British public relations firm Grayling, clinched the contract for S$2.81 million. Its campaign started in the second quarter of 2007, consisting of a website and an album Sounds Of The Underground of ten songs for the purpose.

The LTA has also put up a tender calling for consultants to develop congestion management systems in the KPE. The call has drawn three submissions.[5] It also rolled out the first dedicated team of Traffic Marshals, with the primary role of rapid deployment to any incident within the tunnels. The annual contract was awarded to Certis CISCO, who would deploy six marshals on motorcycles around the clock in the KPE, to be expanded to 28 motorcycles and three cars across all expressways by end 2008.[10]

Speed camerasEdit

KPE's underground section is fitted with digital speed cameras that operate 24 hours throughout the day to enforce the 80 km/h speed limit (as such 70 km/h for some of the tunnel stretches that have G-clamps and WILD system).

The speed cameras are easily spotted in the middle section of the tunnel and are found under the main via ducting. There have been no instances of speed cameras flashes indicating a violating vehicle exceeding the limit, as the luminosity in the tunnel does not require additional light source.
