Singapore Buses route 91

Service 91 is a trunk route from Buona Vista and and looping at Ayer Rajah Crescent, passing through Holland Drive and North Buona Vista Road. It has two looping points, one of which is inside the compound of Ayer Rajah Bus Park.

It 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. It became fully air-con on August 2011, and the last bus route became FAC in July 2016.

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

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.
