Service 115 was introduced as a supplementary route to fill up missing transport links, benefitting residents along a short stretch of Hougang Avenue 3 with a direct bus route to Kovan MRT Station and Kovan City. This service uses the former Hougang South Bus Terminal as its terminating stop. Originally introduced as a six-month trial, the service lives on till today despite its low demand.

Formerly operating at frequencies of over half an hour, additional buses were added under the Bus Services Enhancement Programme (BSEP) which improved frequencies tremendously, down to an average of slightly over 15 minutes. This service was also the very last basic bus service to operate with a single bus.

The last bus timing was extended from 6:15 pm to 8:00 pm daily from 3 May 2021, with no change in the overall number of trips daily.

    Interesting that it doesn’t have a Green/White plate system given how it’s a unidirectional loop, but I guess low demand means why waste resources on it

    Can extend to Hougang int
