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.

Will they use BYD K9s?
I hope lta will give this service to SMRT Buses soon.
Unfortunately 668 went to SBS Transit liao
Which means I can grab service guides
Idk I just call the office just now and they say svc 668 guide cannot be printed due to the covid situation. But I think if u go YCK bus interchange and ask if got svc 668 guide then you can get it
really? SgWiki don’t have one
