99 Turns via SBS Transit Bus Service 200

Bus Service 200 is the only bus service that plies through the full stretch of South Buona Vista Road, which is affectionally known as '99 Turns' due to its numerous winding stretches. While it is indeed factually not 99 turns, it is one of the few remaining roads in Singapore to have its natural curvature left largely untouched.
There are a few bus stops along '99 Turns' which are served by Service 200. A pair of them serve the nearby Science Park Road which is at a lower altitude. A sheltered linkway connects the bus stop to the buildings downhill.
