Work to continue to upgrade Finsbury Park Underground station will begin on April 20 to include step-free access and a bigger station entrance.
Additional changes to the tube station will include new CCTV systems, customer information services and ticket machines.
During the period of construction work, the Wells Terrace entrance will be closed. Ticket barriers will be in operation at Station Place and Seven Sisters Road entrances in order to increase station security.
London Underground Director for Major Programme Sponsorship, David Hughes said: “Finsbury Park Underground station is a busy station which needs to be expanded and improved to cope with the increasing number of people who use the station.”
