During the closures, all main approach roads and surrounding local roads will be extremely busy. Please plan ahead and leave more time for your journey, or use an alternative method of travel or routes. These include:

  • For journeys across London, you can use the M25
  • If you’re travelling to or from central London, you can use the A41, A5 and A1, but allow more time for extra traffic because of the closure
  • Walking, cycling, Tube and National Rail could be quicker ways to travel


Buses in the area will be delayed, diverted, reduced or terminate early. Affected routes include:

  • 32 (diverted via the A5 when the flyover is fully closed, and won’t serve Staples Corner)
  • 112
  • 142
  • 182
  • 232
  • 266
  • N16


Coach services travelling though the area may be diverted or take longer because of these works. Contact your coach operator for details about possible changes to services, and allow plenty of time to travel.
