Bus 145: Shophouses, monuments and cranes

Where: Toa Payoh Interchange to Buona Vista Terminal

Disembark at Block 46 in Holland Drive and walk over to Holland Village for some grub.

Tip: Try to sit on the right side of the bus on this ride, which takes more than 1.5 hours. If you ride in the opposite direction - starting from Buona Vista Terminal - expect different views of Bras Basah, Bugis and Chinatown. It may also be harder to spot the cranes.

Where: Bukit Panjang Interchange to Lim Chu Kang Road (loop service)

The heritage road, stretching between the junction with Ama Keng Road and the junction with Sungei Gedong Road, was built in the 1800s to serve the gambier, pepper and rubber plantations. It used to be lined with single- and two-storey residences and shophouses. and broad-leafed mahogany, angsana and rubber trees can be found here.

Later, near the junction with Neo Tiew Road, you will see the abandoned Neo Tiew estate, which consists of three-storey blocks of flats and had a wet market and playground. Residents moved out in 2002 after an en bloc sale, and has since been used for military training.

Tips: Watch out for traffic if you alight on Lim Chu Kang Road.

The entire route takes about 1.5 hours. Don't do this trip after dark - you won't be able to see much, aside from your reflection here. Also, note that buses leaving Bukit Panjang Interchange after 10.50pm terminate at the Police Coast Guard stop.

Bus 172, which begins at Choa Chu Kang Interchange, will take you down Jalan Bahar where more cemeteries are.

The bus will then drive down Yishun Dam, with scenic views of the water on both sides.
