London Underground has outlined plans to extend the Metropolitan line north of London and build two new stations by 2020.
The company announced today that plans were in place to start construction on the £280m extension of the line through to Watford Junction next year.
The plans include the creation of two new stations in Watford: Cassiobridge and the Watford Vicarage Road station near Watford FC’s ground.
Work will also see a number of bridges and viaducts built along the route.
The existing Watford Metropolitan station will close to the public following the opening of the new stations, but will be retained as sidings for the extended railway.
London Underground confirmed that a funding package for the extension had now been agreed between the Department for Transport, Hertfordshire County Council and Transport for London.
Local funding will provide £125m, the DfT will give £109.8m and TfL will cover the remaining £49m.
London Underground managing director Nick Brown said: “By 2020 we will have built a 400 m viaduct, two completely new stations and numerous new and reconstructed bridges along the route, transforming transport links in Watford.
“With the funding package complete we’re now turning all our attention to appointing contractors, finalising designs and beginning construction in 2016.”
