City Direct Service 670 provides residents of Yishun West 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 Yishun and the CBD via SLE, CTE, Outram Rd and Cantonment Rd.

This is the twentieth 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.
