An underpass in need of refurbishment next to Lister Hospital in Stevenage has been transformed into a work of art by a professional graffiti and mural artist, in tribute to NHS staff. The mural on Coreys Mill Lane has been created by Stevenage artist Mark Tanti - owner of graffiti art service Demograffix - and funded by Hertfordshire County Council. It features an ambulance, air ambulance, rapid response vehicle, Lister Hospital and NHS staff.
