Service 91 serves the Ayer Rajah Industrial Estate with  bus connections to one-north and Buona Vista MRT stations. Formerly operating with many double-deck buses and a shortworking trip in the morning (91A), the opening of the Circle Line (Stage 4) has relieved much of the heavy peak hour demand on this route, and it now operates on a mostly single-deck fleet at low frequencies.

This service has a unique portion of route which enters the compound of Ayer Rajah Bus Park to turn around at at Ayer Rajah Cres.

During morning peak hours, buses cross over to this service from Service 74 to supplement demand. This service does not operate on Sundays and Public Holidays.

Fare: Charges basic distance fares. See Bus Fares. Calculate your bus fare using LTA’s fare calculator on MyTransport.sg here.
