Transport for London (TfL) has said its Northern Line Extension opening date ’is under review’.
The extension will connect Kennington to Battersea via Nine Elms and had been due to open in December 2020.
But TfL’s performance and investment committee said that this date is under review.
A report said: “This is due to the need to adapt the construction programme as the designs for both Battersea Power Station’s oversite development and the tube station underneath it have evolved.”
The extension will serve the new development at Battersea Power Station.
A TfL spokeswoman added: “We are committed to completing the Northern Line Extension.
“TfL is working collaboratively with Battersea Power Station Development Company and we are making good – major tunnelling finished last year and the new and existing Northern line tunnels were connected for the first time.
“Track is being laid in both tunnels and the platforms at the new stations are currently being installed ahead of the further station fit-out next year.”
