Background

Kranji Expressway is Singapore’s eighth expressway.1 Built between 1994 and 1995, it is 8.4km long. It links the Bukit Timah Expressway (BKE) and the Pan-Island Expressway (PIE), at the Tengah flyover, near Hong Kah.2

History

In 1990, the Public Works Department received a S$1.1 billion budget from the government to develop and construct a network of expressways and roads throughout the island over a period of five years.3 This was in tune with the government’s plan to develop the northern and western parts of Singapore into residential and industrial places of choice.4 The road development work included widening, expanding and re-aligning portions of existing expressways, such as the PIE, BKE and CTE (Central Expressway). It also included building underground roads, tunnels, viaducts, semi-expressways and flyovers. The construction of 13 new interchanges and the construction of a road linking BKE and PIE were also included in the plan. This new road was probably named Kranji Expressway as it passed through the Kranji estate in Woodlands, connecting it to Jurong, Choa Chu Kang and Bukit Panjang.5


Construction of the expressway began in April 1990 and it was completed in six stages.6 One of the more difficult jobs in laying the expressway was the clearing of a 1,000 cu m large granite outcrop along the way, for which 300 kg of explosives was used.7 The expressway project comprised five different contracts covering different jobs in the road construction.8

Both the PIE and the AYE were concurrently developed. The PIE was developed at a cost of S$180 million and it was extended until Tuas. Construction of this work began in 1991 and it was completed in 1994.9 Similarly in 1993, the existing Jalan Ahmad Ibrahim was upgraded and extended from Jurong Town Hall Road to Tuas, thus incorporating it into the existing AYE.10 This development was completed in 1997.11 The existing AYE until then only connected the junction of CTE and East Coast Parkway to Jurong Town Hall Road.12

The entire network of linking roads came about by the construction of KJE connecting the BKE in Woodlands to the PIE at Hong Kah,13 the extension of PIE from Hong Kah to Tuas and the extension of AYE from Jurong Town Hall Road to Tuas to join the PIE.14 This extensive network improves accessibility, and enhances residential and industrial development for the western and northern regions of the island.15 Its most marked effect was on the Choa Chu Kang estate which it helped transform from a backwater town into a thriving housing estate.16

Description
The KJE has six flyovers. Beginning at the Tengah Flyover, it is linked to Brickland Road at the Lam San Flyover (Exit 5), to Choa Chu Kang Way at the Choa Chu Kang West Flyover (Exit 4), to Choa Chu Kang Drive at the Choa Chu Kang East Flyover (Exit 3), to Woodlands Road at the Yew Tee Flyover (Exit 2) and to Bukit Timah Road at the Gali Batu Flyover (Exit 1).17

One unique feature of the KJE was the use of a special tar-like asphalt substance as a surface material to minimise the risk of skidding. KJE was one of the first few roads to feature this new surfacing in 1994 which cost S$6.1 million.18 This anti-skid feature was later incorporated into other roads as well.19 The Kranji Expressway was inaugurated on the 4 March 1995 by the Acting Development Minister Lim Hng Kiang.20

Kranji Expressway serves residents of Bukit Panjang, Choa Chu Kang, Bukit Batok and Jurong.21 As it connects Jurong to Woodlands, the expressway is a faster alternative to Malaysians who travel here from Johor to work in factories in Jurong and Tuas.22 Slip roads have been built to provide access between roads at ground level and the expressways.23


Significant construction along the expressway include private and public housing units, most of which were constructed after the laying of the expressway in 1994.24 The Yew Tee MRT which opened with the rest of the Woodlands MRT Line on 10 February 1996 also played a pivotal role in the development of Choa Chu Kang estate.25 The URA released its Development Guide Plan in 1996, soon after the opening of the Yew Tee MRT, with the vision of transforming the Choa Chu Kang estate into a residential district.26
