The Wells Terrace entrance to Finsbury Park Station will close from July 18 for three years while major building works take place. According to TfL, the works will provide step-free access in 2018, reduce congestion and improve security and safety. A new station entrance will open in 2019.
Two new lifts will serve the northbound and southbound Victoria and Piccadilly line platforms, making the station step-free from street level to the trains. Further details from TfL can be found here.
