I think you mean Watford (Metropolitan) to close rather than Watford North, which is on the Abbey Line to St Albans.
The plan is to build a viaduct from the Metropolitan Line just to the north of Croxley Station (Met) take it across a main road and the canal and join the extant Croxley Green Branch at Ascot Road. The existing bridge over the canal will be abandoned as will the section of line from Ascot Road to Croxley Green Station.
Also being closed would be the section of track on the Metropolitan Line from the point where this new viaduct is built to Watford (Met) Station.

UK▸ network.
