Before the opening of Sembawang Bus Interchange, various bus services terminated at scattered parts of Sembawang town. These include Admiralty Road West Bus Terminal for Service 980, Sembawang Road End Bus Terminal (near
Sembawang Park) for Service 167 and the pair of bus stops outside
Sembawang MRT station for Service 981. When Sembawang bus interchange opened, these bus services, along with Service 859, which operates from
Yishun Bus Interchange, were amended to terminate at the newly opened bus interchange. Bus Service 882 was introduced to replace the lost link between Sembawang and
Sembawang Park along Sembawang Road End (via Wellington Circle and Montreal Link). The link by former services to the former Admiralty Road West Bus Terminal from Sembawang were covered by Service 856 and Service 981. Service 856 passes by both places along its route between
Yishun Bus Interchange and
Woodlands Bus Interchange, while Service 981 passes by both place on its route to
Senoko Industrial Estate. Since then, due to the Bus Service Enhancement Programme Singapore (BSEP), four new bus services were introduced to Sembawang: Service 859A & 859B in 2014 as supplementary services, Service 117 to Punggol in 2015 and Service 883 to loop at Yishun Central 2 in 2016. Service 883M was introduced in 2020, looping at Yishun Avenue 5 to supplement Service 883, while Service 117M was introduced in 2021. Services 117M & 883M were not introduced under the BSEP. Service 167 was degraded several times since COVID-19 pandemic, with the frequency dropping to 30 minute intervals on 17 December 2023. On 15 September 2024, Bus service 861 was introduced, looping at
Khatib MRT station, connecting Canberra with Yishun East & Khatib. This is the first bus service introduced under the Bus Connectivity Enhancement Programme (BCEP), which was launched by the
LTA on 30 July 2024. == Management ==
