Green Lanes, London, (N16, N4, N8, N13 and N21) is a main road in North London and forms part of the A105. Covering a distance of 6.3 miles (10.14 km) between Newington Green and Winchmore Hill, it is one of the longest streets in the capital.
Green Lanes is an ancient thoroughfare, originally a drovers' road along which cattle were walked from Hertfordshire towards Smithfield Market in London.
It runs from Newington Green north along the western edge of Stoke Newington, thereby forming the border between Hackney and Islington, until it reaches Manor House at the eastern edge of Finsbury Park. Entering the London Borough of Haringey, it then runs 1.4 miles (2.25 km) through the neighbourhood of Harringay. From the junction with Turnpike Lane the road temporarily changes its name and runs for 1.3 miles (2.1 km) through Wood Green as 'High Road', resuming its Green Lanes identity again after the junction with Lascotts Avenue. It then continues north for another 2.2 miles (3.5 km) through Palmers Green and Winchmore Hill in the London Borough of Enfield, until it reaches the junction with Ridge Avenue and Green Dragon Lane at Mason's Corner. The northward continuation into Bush Hill at this point is now blocked.
