I'm travelling northbound over the Dartford crossing (from A2) on Friday evening to try to avoid the Olympic traffic on A12. I just wondered what time Friday rush hour is over around there as I'd like to avoid traffic if possible.
Lakeside is a designated park and ride location for the Games. So is Ebbsfleet just off the A2 from where the Javelin train will get you to Stratford International in 11 minutes.
