Sengkang Bus Interchange

Sengkang Bus Interchange is a bus interchange located on the ground level of Compass Heights condominium in the town centre of Sengkang New Town. Located next to Sengkang MRT/LRT Station, Sengkang Bus Interchange is the second bus interchange in Singapore and the first bus interchange along the North East Line to be air conditioned. It was opened on 18 January 2003.

Old bus interchange
The bus interchange was opened on 12 June 1998 as a terminal. At that time, developments around the area in Sengkang New Town were still actively in progress. On 28 April 2001, the bus interchange was located across the road of Sengkang Square.

Relocation
On 18 January 2003, after the Sengkang LRT East Loop opens, Sengkang Bus Interchange is moved to Compass Point Shopping Centre, and is integrated with the other transport networks like the Sengkang MRT, Sengkang LRT line and station, all housed under one complex. It is notably the second bus interchange in Singapore to be air-conditioned, after Toa Payoh Bus Interchange.

Enhancement
To improve ventilation at the former non-air conditioned alighting bays, the Land Transport Authority constructed a new air-conditioned passageway connecting to the existing air conditioned boarding areas in 2007.

Change of bus routes
Service 27, which used to ply between Sengkang Temporary Bus Interchange and Singapore Changi Airport, was extended to Hougang Central Bus Interchange on 29 December 2002.

Service 85, 501, and 502, which used to ply from Sengkang Bus Interchange to HarbourFront, Marina Centre and Boon Lay respectively, were removed or re-routed to prevent duplication of the North East Line when the North East Line was opened on 20 June 2003. After public feedback and consultation with schools whose students were affected by the withdrawal of Service 85, Service 119 was introduced to replace a segment of Service 85's route between Sengkang and Hougang Street 21.

Service 371 was re-routed when the East loop of the Sengkang MRT/LRT was opened on 20 January 2003, and removed when the West loop opened on 29 January 2005. To complement the West Loop LRT service after the removal of Service 371, Service 163A (later renumbered as 163M) was introduced, and runs at specific timings throughout the day.

On 21 October 2012, under the Bus Service Enhancement Programme (BSEP), Service 119 was extended to terminate at Punggol Bus Interchange instead of terminating at Sengkang Bus Interchange, calling at an additional four pairs of bus stops.
