Bus Service 90

SBS Transit Bus Service 90 is an industrial route linking the residential estates of Toa Payoh to industrial estates along Airport Road and the Paya Lebar Air Base (PLAB). The route alleviates the demand from Service 8 between Toa Payoh Central and MacPherson Road.

Short-Trip Service 90A supplements the industrial and military demand from Toa Payoh Interchange to Airport Road, operating during the weekday and Saturday morning peak hours.
