2017 Route Amendment

From Sunday, 30 July 2017, Service 123 will be amended to terminate at Beach Station Terminal within Sentosa Island, calling at intermediate stops along Artillery Avenue. It will also call at Resorts World Sentosa in the direction of Beach Station only. The route will enhance connectivity to Sentosa Island, linking it with Tiong Bahru MRT Station and the Orchard Road shopping belt.

The route amendment will make Service 123 the first regular trunk service to terminate at Sentosa. Currently, Express Services 188R and 963R terminate at Sentosa, which operate only on weekends and public holidays and charge express fares.

Service 123M will not be amended, and will continue to offer connections between HarbourFront Bus Interchange and Tiong Bahru.

White plated Service 123 buses will head towards Beach Station instead of Harbourfront.
