Repairs will start on Saturday, February 14, and are expected to last up to two weeks. The work will cause delays eastbound A406 towards Brent Cross and will impact the Hanger Lane Gyratory System. The junction from Hanger Lane heading eastbound onto the North Circular will have lanes one and two closed. Engineers will be carrying out the work between the hours of 8am and 8pm, with some night-time activity where required. More than 2,000 residents have been notified of the work and Thames Water staff will be visiting impacted businesses.
