Outer Ring Road System

What is ORRS?

The Outer Ring Road System (ORRS) is a network of major roads that forms a 'ring' along the outer areas of the city.

It is extensively linked to expressways and other major roads, allowing motorists to get from one traffic route to another easily.

How does ORRS benefit motorists?

Through ORRS, motorists can:

  • travel between the east and west of Singapore without going through the city
  • expect reduced traffic volume on city-bound roads
  • get to major roads such as Bukit Timah easily.


Upgrading Works

Since 1994, roads along the ORRS have been upgraded in stages to provide a smoother route to travel across the island.

The road upgrading works along ORRS at Farrer Road, to 4 lanes along Holland and Adam bound were completed and opened to traffic on 21 November 2010.

The pedestrian overhead bridge along Farrer Road, in front of Block 2 and Block 6A were completed and opened to the public on 29 September 2010.


ConstRuction of New Road BETWEEN MacRitchie Viaduct and Adam Flyover VIA Bukit Brown Cemetery

A new dual four-lane road will be constructed off Lornie Rd, between MacRitchie viaduct and Adam flyover to ease congestion along the Pan-Island Expressway (PIE) and Lornie Rd during peak hours.

A total of 3,746 graves out of the more than 100,000 graves currently sited at Bukit Brown cemetery will be affected by the construction of the new road and has to be exhumed. Some of the graves in Seh Ong Cemetery, located to the left of Bukit Brown near Adam Flyover, will also be exhumed.


When will construction start?

Construction of the new road will begin in stages after exhumation of affected graves are completed. While construction is on-going, members of the public can still continue to enter the other parts of the Bukit Brown cemetery that are not affected by the road construction. The details of the routes will be made available to the public when construction starts. The new road is planned to be completed by end of 2017.


What happens to the affected graves?

LTA is undertaking the exhumation of the affected graves. Public exhumation of the affected graves will begin from 4Q 2013. LTA will be contacting the next-of-kin of affected graves who had registered their claims to make arrangements for exhumation.

Next-of-kin of affected graves can register their claims for the affected graves with us.
