SMRT 405 Hyperlapse (Loop) HALLOWEEN SPECIAL

Happy Halloween 2025

Bus Service 405 directly connects Choa Chu Kang Cemetery, Crematorium and Columbariums & Nirvana Memorial Garden with Boon Lay MRT/Bus Interchange, serving Old Choa Chu Kang Road. Buses perform a 3 point turn at the end of Old Choa Chu Kang Road.

This service operates only during specific periods: the Qing Ming Festival, Good Friday, the start of Ramadan, Hari Raya Puasa, Hari Raya Haji, the Deepavali period, and All Souls' Day. The exact operating dates are announced by the bus operator closer to each year's start of service.

During the Singapore SEA Games in June 2015, a special variant of Service 405, known as Service 405M, ran for six days to serve the National Shooting Centre on Old Choa Chu Kang Road, bypassing the Lim Chu Kang Road section of the route.

In October 2025, Service 405 was amended to the realigned Jln Bahar and skip Lim Chu Kang Road following the closure of part of Lim Chu Kang Road to facilitate the expansion of Tengah Air Base on 8 June 2025. Lost sectors included a unique U-turn point along Lim Chu Kang Road, just before Murai Farmway, where a special "Bus-only" U-turn bay is utilized.
