COMMUTERS will face delays this week while phone signal upgrade works take place.

Drivers in Wanstead, South Woodford, and the surrounding areas should expect queues at the Granville Road junction of Chigwell Road until Wednesday (March 22).

Temporary traffic lights are being used at the junction for O2 to carry out upgrades on two of their telecom cabinets.

The work will take place between 9.30am and 3.30pm each day, affecting school runs and M11 and A406 North Circular commuters.
