22-621: The Outer Ring Road System , or more commonly known as ORRS , is a network of major arterial roads in Singapore that forms a ring road through the towns along the city fringe. The ORRS is a semi-expressway, just like the West Coast Highway . Since 1994, roads along the ORRS have been upgraded in stages to provide a smoother route to travel across the island . Roads and interchanges along the ORRS are constantly being upgraded to cater to

44-416: A 1-metre hard shoulder . At a length of 5 km, the viaduct is the longest in Singapore. The Land Transport Authority started modifying and extending the highway in the late 1990s, in response to the increased amount of traffic using it. Its intersection with Clementi Road was widened in 2000. To allow motorists to bypass intersections at Pasir Panjang Road , LTA's plans also called for the construction of

66-619: A clockwise direction, the route begins at Queenstown with a connection to the Ayer Rajah Expressway . The route continues northward through the residential areas of Bukit Timah via Farrer Road and Adam Road, with the first connection to the Pan Island Expressway . The route continues east through Bukit Brown , Toa Payoh , Bishan and Bartley , via the MacRitchie Viaduct and Lornie Viaduct and

88-639: A connection to the Central Expressway . From here, the route travels eastwards to Kaki Bukit and Tampines through a series of viaducts . With the ORRS, traffic volume on city-bound roads will be reduced. It also provides an alternative route east-west travel for motorists without going through the city. Since ORRS is extensively linked to expressways and other arterial roads, such as Bukit Timah Road , motorists can get from one traffic route to another easily. The first upgrading project started in 1994, with two intersections along Farrer Road being

110-462: A new contractor to finish the work. On 1 August 2005, LTA awarded the contract to Gammon , which completed the remaining work on schedule in March 2006. The viaduct's completion was commemorated with an opening ceremony and fun walk on 25 March 2006, with the then Minister for Transport Yeo Cheow Tong officiating; it was opened to traffic on 26 March 2006. At the same time, the intersection of

132-409: A new dual three-lane flyover at the junction of West Coast Highway and Clementi Road started. The flyover will cost S$ 57.5 million. The flyover allows motorists to bypass the current traffic light junction and shorten travel time along the highway. The flyover was completed in the third quarter of 2011. There are 2 entry ramps for the entire viaduct travelling towards the city – one at its start before

154-455: A viaduct that would provide a direct link from the highway to Keppel Road on the outskirts of the city area. The viaduct was built in two phases of 2.4 km each. The first phase, from Keppel Road to Telok Blangah Street 31, started construction in 1998 and was opened to traffic on 27 April 2002. The contract to build the second phase of the viaduct from Telok Blangah Street 31 to the highway's junction with Pasir Panjang Road, worth S$ 16.7 million,

176-408: Is 11 km. The viaduct is newer than the at-grade section, having been completed in 2006. Despite what its name may suggest, the speed limit on the highway is less than that of an expressway. The highway also has a few traffic light junctions, something that expressways do not have. The at-grade section of the highway is a three-lane dual carriageway , and the viaduct is a two-lane dual carriageway with

198-404: Is a major arterial road in Singapore which links Jurong industrial estate and Clementi New Town to the city. It is an at-grade road from its junction with Pandan Loop and West Coast Road to its interchange with Pasir Panjang Road, where it becomes a grade-separated viaduct ; the viaduct merges with Keppel Road before its interchange with Ayer Rajah Expressway . The total length of the highway

220-519: Is expected to raise PSA's container handling capacity by a further 18 million  twenty-foot equivalent units  (TEU) per year. The terminal's first four berths , of the planned 26, opened in 1998, with two more berths becoming operational by the time of the terminal's official opening in March 2000. The terminal is slated to cease operations by the year 2040 when the Tuas Megaport is completed and all of PSA assets will be transferred to

242-655: The Singapore River to Jurong , has been reclaimed for wharves , almost entirely devoted to containerisation . The coastal area at Pasir Panjang has also been extensively reclaimed for the Pasir Panjang Terminal of the Port of Singapore .

264-540: The ever increasing traffic demand. It starts as Portsdown Avenue in Queenstown and ends as Tampines Avenue 10 in Tampines . The series of roads passes through the areas of Queenstown, Bukit Timah , Central Catchment Nature Reserve , Bishan , Toa Payoh , Geylang and Tampines . The route of the ORRS forms a semi-circle shape, connecting several expressways and major arterial roads. Travelling from west to east in

286-684: The first to be upgraded. The upgrading projects had to be carried out in stages to minimise disruption to traffic. The completion of the Portsdown Flyover, Queensway Flyover and Queensway Underpass marks another milestone in the realisation of the ORRS. The Farrer Road section of the upgrading project completed in 2009. ^Note 1  : Only expressways , arterial roads and major roads will be mentioned. Minor roads will not be mentioned.

308-567: The highway with Jalan Buroh was converted from a box junction into a controlled roundabout with traffic lights. A slip road allows motorists to get to Jalan Buroh from the direction of the city without having to stop. The conversion started in May 2001 and was completed in the third quarter of 2005. The roundabout was converted back into a box junction after the opening of a new flyover across Jalan Buroh in November 2016. In May 2009 construction of

330-499: The junction with Pasir Panjang Road, and another after the junction with Morse Road, near Henderson Road. Thus, city-bound motorists who miss the entry ramp at Pasir Panjang will have to travel for another 2.4 km – half the length of the viaduct – before they can get onto it at Morse Road. There are 2 exit ramps – a U-shaped one just before Kampong Bahru Road, intended for vehicles going to the Keppel and Pulau Brani container terminals, and

352-458: The local residents of the many Malay kampungs dotted around the road and area with the security of a police presence. The old building was torn down in 1991 and the land levelled.

374-449: The new port. COSCO Shipping Ports , formerly COSCO Pacific , is a co-investor. In 1986, the old Singapore Police Force Pasir Panjang Police Sub-station was vacated after almost 4 decades of service, its duty and areas of jurisdiction taken over by Pasir Panjang NPP and West Coast NPP respectively. Originally constructed in 1950, its location near the crossroad junction of Clementi Road, Pasir Panjang Road and West Coast Road provided

396-406: The other one after Kampong Bahru Road, where the viaduct merges with Keppel Road. Travelling towards Clementi, there is one entry ramp – before Kampong Bahru Road. There are three exit ramps, one before Henderson Road, one before Alexandra Road and another after Pasir Panjang Road. West Coast Highway passes by the following places: Pasir Panjang Road Pasir Panjang is an area located at

418-591: The southern part of Queenstown in Singapore . Kent Ridge Park is a topographical feature which runs adjacent to Pasir Panjang. Pasir Panjang Road, which once hugged the coastline , was laid down as far as the Jurong River by John Turnbull Thomson by 1850. Thomson was Government Surveyor of Singapore from 1841 to 1853. In 1910, the Government took over the opium industry and a state-owned factory

In 1993, the Port of Singapore Authority (PSA), now corporatised as PSA International , started constructing a new container terminal at Pasir Panjang, the Pasir Panjang Terminal. it is located approximately 7 km west of the company's other container terminals at Keppel Harbour . This new, S$ 7 billion terminal, represents an immense expansion of PSA's container port. When fully completed in 2009, it

462-506: Was awarded to L&M Prestressing in January 2000, and the viaduct was expected to be complete by July 2003. However, work slowed in late 2002 because L&M encountered financial problems. L&M then promised LTA that the viaduct would be completed in May 2005. LTA agreed to give the company time to complete it, but when work had still not finished by that time, LTA terminated the contract on 1 June 2005 and called for an open tender to find
