Rubbing their eyes in surprise, early risers in Palmers Green may have seen the after affects of a massive Road Traffic Collision on Aldermans Hill circa 17th October 2014

In the absence of any images on Twitter:

• the No entry sign was demolished;
• the Keep left sign was demolished

•  from the marks and oil deposits, one of the vehicles arrived on the footway outside of Nationwide

Anyone trying to reach Bowes on bus route 121 will have had a hard time.

Can anyone shed any more information on the incident, please?
