From 22:00 on Friday 21 October, there will be closures to the A1 Holloway Road at Upper Holloway. This is while we build a stronger bridge and carry out additional works due to unforeseeable complications while moving pipes and cables from the existing bridge.
The installation of the new bridge at the end of December will allow Network Rail to complete the electrification of the Gospel Oak to Barking London Overground line.
The A1 Holloway Road will be fully closed in both directions between Fairbridge Road and Wedmore Gardens from:
• 22:00 Friday 21 until 05:00 Monday 31 October
• 22:00 Friday 18 until 05:00 Monday 21 November
• 22:00 Friday 25 until 05:00 Monday 28 November
• Saturday 24 December until Monday 16 January
From 05:00 Monday 31 October until Saturday 24 December the road will be closed southbound only.
Traffic will be diverted via Junction Road and Tufnell Park Road or Brecknock Road. Drivers heading into central London from the M1 and M25 may want to consider using the A5, A41 and A10. We will do everything we can to complete the work as quickly as possible but roads in and around the area are expected to be busier than usual, especially during peak hours. Buses will be delayed, diverted or stop short of their normal destination. Access for pedestrians and cyclists will be maintained, but cyclists will need to dismount and walk.
