SBS Transit City Direct Bus Service 668

SBS Transit City Direct Bus Service 668 is a Weekday Peak Hour City Direct Service between Ang Mo Kio / Yio Chu Kang and the Central Business District, passing through Ang Mo Kio St 52. It is the eighteenth City Direct route introduced under the Bus Service Enhancement Programme (BSEP).

City Direct Service 668 provides residents of Yio Chu Kang and Ang Mo Kio with greater connectivity to the CBD. The service provides a travel alternative for commuters who relied on the rail network and feeder buses to and from work. The route incorporates an express sector between Ang Mo Kio and the CBD via CTE, Outram Rd and Cantonment Rd.

This is the eighteenth City Direct service to be introduced under the Bus Service Enhancement Programme (BSEP), which provides more options for commuters using stretches of the existing rail lines that experience persistently high ridership, while the ongoing rail enhancement measures are being implemented.

Bus Service 668 was the last City Direct bus service to be handed over from Private Bus Operators to Public Transport Operators. The last evening trip on 11 December 2020 was performed by PC4308G.

If the eves of Christmas, New Year’s Day, and Chinese New Year fall on a weekday, the Evening Peak departures will be brought forward to the afternoon. Revised departure times will be provided by the operator closer to the affected date.
