Singapore Buses route 115

Service 115 is a residential trunk route from Hougang Street 21 and looping at Hougang Avenue 3, passing through Hougang Avenue 1 and Kovan MRT station. It is currently the only service terminating at Hougang Street 21, the former Hougang South Bus Interchange.

Because of low demand and under-utilization, Service 115 was slated for withdrawal many years ago, but continues operating at the request from local Members of Parliament. Today, only one bus is deployed, with frequencies at half an hour. With no mealbreak crossover buses, the longest wait for a single bus is 50 minutes (11:45 to 12:35), the longest of any scheduled bus service. It was the last basic service to operate on a single bus.
