The funding package for the Metropolitan Line Extension project has been finalised, London Underground announced on 23 November. Construction is now expected to start next year, with completion due in 2020.

A full funding package for the extension has now been agreed between the Department for Transport (DfT), Hertfordshire County Council and Transport for London (TfL), and the work will be delivered by LU.

The £284·4m cost includes a local contribution of £125·4m, £109·8m from the Department for Transport and £49·2m from Transport for London. The local funding includes £87·9m from Hertfordshire LEP, which represents 40 per cent of our total Growth Deal funding from Government.

Hertfordshire LEP Chairman John Gourd said: “We have worked hard with our partners including Hertfordshire County Council and Watford Borough Council and are delighted to have now reached this exciting stage.

"The Metropolitan Line Extension will unlock investment in brownfield sites, revitalise existing employment areas and bring considerable job opportunities and economic benefits to Watford and the wider community.

"As the second largest funder this demonstrates the huge importance that we attach to this project which will help realise our priority to deliver at least 1,400 jobs in the M1/M25 area by 2021.”

The Metropolitan Line Extension will support growth and regeneration in and around Watford by making journeys to and from London easier. The Underground will be connected to the West Coast Mainline via the station at Watford Junction, and the two new stations will also provide new connections to Watford General Hospital and new Health Campus, Croxley Business Park and Cardiff Road Industrial Estate.
