Circle Line completion guide: Closing the loop in Singapore

The Circle Line (the orange line, station codes prefixed CC) is finally a complete, closed loop. The opening of Circle Line Stage 6 joins the south at HarbourFront (CC29) to the east/financial district at Marina Bay (CC33) through three new stations: Keppel (CC30), Cantonment (CC31), and Prince Edward Road (CC32).

This completion eliminates awkward transfers and bridges a critical gap in Singapore's transit map, changing how commuters travel between the west, south, and the Central Business District (CBD).

• Orange line, station codes start with CC
• Closes the loop between HarbourFront and Marina Bay
• Three new stations: Keppel, Cantonment, Prince Edward Road

The 3 New Stations

Closing the circle required building three new underground stations along the southern edge of the city:

• Keppel (CC30) — Located along Keppel Road, serving the future Greater Southern Waterfront district and nearby maritime offices.
• Cantonment (CC31) — Integrated with the historic Tanjong Pagar Railway Station site, serving Spottiswoode Park and Cantonment Road residents.
• Prince Edward Road (CC32) — Positioned near Palmer Road and Shenton Way, providing direct rail access to the southern commercial core.

Before vs. After: Commutes Reimagined

By closing the gap between HarbourFront and Marina Bay, the Circle Line removes the need to route through already crowded city-centre interchange stations.

Here is how common commutes look now:

HarbourFront to Marina Bay

• Before: Commuters had to take the North-East Line (purple) to Outram Park, transfer to the East-West Line (green) to Raffles Place, and transfer again to the North-South Line (red) to Marina Bay. Alternatively, riding the Circle Line all the way around via Dhoby Ghaut took nearly 40 minutes.
• After: A direct, single-train ride taking approximately 10–12 minutes.

Kent Ridge (NUH) to Marina Bay

• Before: Travel required heading to Buona Vista, transferring to the East-West Line to Raffles Place, and then changing to the North-South Line.
• After: A direct train along the southern loop straight to Marina Bay, cutting travel time by nearly 15 minutes and removing two transfers.

Pasir Panjang to Tanjong Pagar (Shenton Way area)

• Before: Commuters had to transfer to buses at HarbourFront or navigate multiple MRT transfers.
• After: Alight directly at Prince Edward Road (CC32) or Cantonment (CC31) with zero transfers.

How does a closed loop change routing?

Unlike standard lines with clear endpoints (like Pasir Ris to Tuas Link), a completed Circle Line runs continuously in two directions:

1. Inner Loop (counter-clockwise)
2. Outer Loop (clockwise)

For stations on opposite sides of the loop (e.g., Caldecott to HarbourFront), going clockwise or counter-clockwise takes almost the exact same time. But for most other trips, choosing the correct direction is the difference between a 10-minute ride and a 40-minute tour of the island.

Plan your new route with MRT Go

MRT Go has been updated with the completed Circle Line loop, including Keppel, Cantonment, and Prince Edward Road stations. When you plan a trip, the router automatically calculates whether the clockwise or counter-clockwise loop is faster and gives you the exact transfer points.
