Drivers are being warned to avoid sections of the A406 this week as Transport for London (TfL) carry maintenance works as parts of its road modernisation plan. 

The North Circular Road will be closed eastbound between Angel Road in Edmonton and Hall Lane in Chingford from 10pm on Friday (March 27) and 5am on Monday (March 30).  

Works are specifically focusing on the Lea Valley viaduct. 

A diversion will be in place using the slip road's either side of the viaduct. Delays are expected around Walthamstow Avenue and Billet roundabout and Angel Lane in Edmonton.  

Drivers are encouraged to use the M25 if possible and buses 33 and 444 may stop short of their normal journey destination.
