Long traffic delays are expected in the Totteridge and Mill Hill area for the next three months as Three Valleys Water carries out repairs to water mains.

Roadworks began on Tuesday morning, closing the junction of Marsh Lane and Highwood Hill, causing significant tailbacks along Totteridge Lane and up Highwood Hill. It means westbound traffic aiming for the A1 or A41 at Apex Corner is being diverted along Highwood Hill and along Lawrence Street to Mill Hill Circus.

Barnet Council says the roadworks are expected to continue until February 2007.
