Tottenham one-way shut Sunday

Sunday – the Tottenham one-way system is shut today during a crime scene investigation. It’s causing the expected chaos:
Severe delays and road closed due to police incident on A503 Forest Road / Broad Lane / Fountayne Road Westbound between A1006 Blackhorse Road (Blackhorse Road Station) and A10 High Road (Seven Sisters). Closed since around 06:00 this morning because of a stabbing in the Broad Lane part of the Tottenham Hale one way system. Closures are in place from Blackhorse Road Station, and Watermead Way from Northumberland Park as a result. Major delays in the area. Diversion: Southbound traffic on the A10 is diverted north up Watermead Way, or east to Blackhorse Road. Traffic wishing to get from Bruce Grove towards Stamford Hill will have to divert via side streets or past Turnpike Lane Station. [from Haringey Independent]

Basically, forget it. It just took me nearly three hours to drive to Seven Sisters from Ally Pally.
