The Outer Ring Road System (ORRS) is a network of major roads that forms a 'ring' along the outer areas of the city. It provides an alternative route for motorists to travel between the east and west of Singapore without going through the city. Hence, it helps to reduce the traffic volume on city-bound roads.

The ORRS network includes Queensway, Farrer Road, Adam Road, Lornie Road, Braddell Road, Bartley Road, Eunos Link and Still Road. It is extensively linked to expressways and other arterial roads, allowing motorists to get from one traffic route to another easily.

The roads along the ORRS are being upgraded to provide smoother travelling. The upgrading started in 1994 at two junctions along Farrer Road and is carried out in stages at other locations to minimise disruption to traffic.

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.

Lornie Road is part of the Outer Ring Road System and allows motorists to travel from the east to the west while bypassing the city. It also serves as an essential road connection for traffic between PIE and residential estates in the central and northern parts of the island, such as Ang Mo Kio, Bishan and Thomson.

By 2020, traffic demand is expected to increase by 20% to 30% due to upcoming development in the central and northern parts of Singapore, more than the current capacity of Lornie Road.

A dual four-lane road will be constructed in the Bukit Brown area to alleviate the congestion along Lornie Road and the Pan Island Expressway (PIE), and help ease the traffic demand from future developments in the area. The new road will also form part of the road network that support future housing plan in Bukit Brown Area.

The new road will connect the existing Thomson Road near Caldecott Hill and will cut through parts of the existing Bukit Brown Cemetery before joining Adam Road near the slip roads leading onto PIE.

Construction is expected to commence in the first quarter of 2013 and be completed in 2016.
