Route Extension of Service 991 to Choa Chu Kang with the Integration of Service 308
When Service 991 was launched in July 2018, the service looped at Bukit Batok West Avenue 5 from Bukit Batok Bus Interchange, as part of Bukit Batok West Avenue 5 between the junction with Bukit Batok West Avenue 9 and Bukit Batok West Avenue 2 was still under construction.
New Short-Trip Service 991B will also be introduced from 30 September 2018, operating from Choa Chu Kang Bus Interchange and terminating at Choa Chu Kang Avenue 1 (Opp Choa Chu Kang Mkt) between 0018hrs and 0055hrs daily.
A pair of bus stops along Brickland Road (Bus Stop 30109 – Opp Blk 485A & Bus Stop 30101 – Blk 485B) are slated as future bus stops.
With the route extension of Service 991 to Choa Chu Kang incorporating part the SMRT Feeder Bus Service 308 route, Service 308 between Choa Chu Kang and Keat Hong Link will be withdrawn. Commuters travelling to existing bus stops served by Service 308 can take alternative Services 172, 983 and 991.
