NORTHERN LINE: Saturday 7 and Sunday 8 September, no service between Golders Green and Edgware (including Friday and Saturday Night Tube). Replacement bus service NL1 operates between Golders Green (Golders Green Road) and Canons Park (for Jubilee line) via Brent Cross (Golders Green Road), Hendon Central, Colindale (Colindale Gardens and Colindale Avenue), Burnt Oak and Edgware. Night journeys do not serve Canons Park. NOTE: Due to a road closure of Colindale Avenue between 2200 and 0500 on Friday night, and between 2200 and 0900 Saturday and Sunday nights, replacement bus NL1 will not serve the Colindale Avenue stop at these times. In addition, at Burnt Oak, buses will serve stops in Orange Hill Road (Watling Avenue / Park Croft) instead of Watling Avenue. Local bus routes will also be affected by this road closure.
