Bus Service 405 connects Choa Chu Kang Cemetery, Crematorium and Columbariums with Boon Lay MRT/Bus Interchange, serving parts of Old Choa Chu Kang Road and Lim Chu Kang Road without a regular bus service.

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.

Service 405 features two unique U-turn points. The first is at the end of Old Choa Chu Kang Road, at the junction with Jalan Sungei Poyan, where a three-point turn is performed. The second is on Lim Chu Kang Road, just before Murai Farmway, where a special "Bus-only" U-turn bay is utilized.

On certain days with exceptionally high traffic on Old Choa Chu Kang Road, buses may be diverted to skip this road altogether, looping at Lim Chu Kang Road before returning to Boon Lay.

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.

The service is planned to be shortened to skip Lim Chu Kang Road from 2Q 2025 due to the realignment of Lim Chu Kang Road as part of the Tengah Airbase expansion.

• Choa Chu Kang Columbarium
• Choa Chu Kang Crematorium
