In the north of London Green Lanes stretches from Newington Green in Stoke Newington N16 all the way up to its junction with Ridge Avenue in Winchmore Hill, N21. At a distance of about 7.5 miles, this makes it a candidate for the longest street. However, in the relatively recent past the stretch that runs through Wood Green has come to be known as High Street, only resuming the Green Lanes name at the borough boundary between Enfield & Haringey.
The stretch of Green Lanes from Newington Green up to the point when it becomes High Road for a while measures 3.2 miles. So, even that part is longer than Rotherhithe Street.
