Bus service 381 launched on 12 March 2017, originally running from Punggol Bus Interchange in a loop through Punggol East. Operated by Go-Ahead, it added local connections to transport facilities, shopping destinations and schools.
Punggol bus 381 changed substantially on 13 September 2026, when it extended to Punggol Coast Interchange and became a two-direction service between interchanges. The original Punggol East loop and the later coast connection belong to different stages of its history.
For readers asking when bus 381 began, the answer is March 2017. For those asking when it reached Punggol Coast, the relevant milestone is September 2026. Keeping both dates visible explains why earlier route posters show a loop rather than two endpoints.

What the March 2017 launch connected · The September 2026 Punggol Coast extension · Why the two stages matter
The LTA and Go-Ahead launch poster confirmed the Sunday start and described connections from Punggol East to Punggol MRT/LRT and the interchange. It also highlighted Waterway Point and Punggol Plaza.
The poster named Edgefield Primary, Horizon Primary, Greendale Primary, Greendale Secondary and Waterway Primary among the schools along the connection. Its map traced a neighbourhood route using Punggol Field, Punggol Way, Punggol Central, Edgefield Plains and Punggol East.
LTA’s September 2026 programme annex dates the extension to 13 September. It identifies improved travel between Punggol East and Punggol Coast, with connections to the coast transport hub, mall and SIT campus, plus Punggol Polyclinic en route.
Land Transport Guru’s updated chronology records the conversion to a bi-directional service. This was more than adding a stop: the route changed from returning around a loop to operating between two interchanges.

Our interpretation is that bus 381 shows a changing relationship between neighbourhood and town centre. The first stage connected Punggol East with established local destinations; the extension connected it with the growing coast centre as well.
For a remembered journey, start with the year of the map or photograph. A 2017 poster and a 2026 route description need not contradict one another. Follow the wider sequence of interchange, rail and community openings through the Punggol history directory.
