Green Lanes is one of the main routes through Palmers Green, running north to south through the shopping parade and connecting the A406 North Circular with the residential streets around Princes Avenue.
It is the third London road to be shut overnight for crash investigation work in the past 24 hours. High Road Leyton was closed for more than 12 hours after an incident on Thursday night, and Wood Lane in Barking was closed in both directions while crash investigation work continued — that closure has now been lifted.
