Plans to build the sixth stage of the Circle Line are underway.

In a joint announcement on Wednesday, the Land Transport Authority and Singapore Land Authority said a parcel of land at PSA Corp's Keppel Terminal will be acquired to facilitate construction for the extension of the train line.

Affected facilities on-site include a one-storey port facility and part of the internal circulation road. The SLA has gazetted the land affected by the acquisition.

Stage 6 of the Circle Line will make the orbital a complete circle when it is completed in 2025.
