Route History

Service 106 serves the residential estates of Bukit Batok, Clementi and Buona Vista, providing a direct bus connection to the Orchard Road and Downtown Core areas. It is a vital connection not just between residential estates, but also many It also offers many links within different parts of the city, such as Orchard Road, Bras Basah, Marina Centre, Marina Bay Sands, Downtown and Shenton Way.

Service 106 offers the fastest bus connection between Bukit Batok and Clementi, and apart from express services, is the only bus route connecting the Orchard shopping belt with Marina Bay Sands and surrounding attractions at Bayfront.

    1. This morning Service 106, bus registration number SMB3518P had 4 standing passengers on the upper deck whom they boarded at the Holland Village bus stop. They were standing all the way to bus stop at Gleneagles.
    Please remind the bus captains to constantly view their CCTVs especially when the bus is crowded.

    2. It’s been a month since Tower Transit has taken over this Service 106. But I hae yet to see any positive improvement in the schedules. At worst, I see a 106A arriving at the bus stop and a 106 arriving less than a minute(depending on traffic light signals). Then when I boarded this 106, after some distance along Commonwealth Ave West, there’ll be another 106 overtaking and thereafter these two 106s will be taking turns to trail each other. I board service 106 at bus stop 20109, block 203 daily just before 8am.
