There is a joke in London that taxi driver don't go "south of the river", well, come the Olympics, no one in a car is going to be going south of the river, not if you take a look at the maps on the Olympic Route Network.
There will no longer be the opportunity to come down the M11 and go through Blackwall - as I have to regularly. No, you;ll have to go via the Woolwich Ferry (although that is designated as an "alternative route" should there be other problems so you may, as an ordinary citizen be banned from that way too).
That leaves you with Dartford, which, is utterly congested at the best of times and will be absolute utter chaos during the Olympics.
Still.. it's only two weeks right? Errr no. This seems to suggest that the so-called "Olympic Route Network" will operate from July 2012 to September 2012 (two months).
Joy! Gridlocked areas being redirected to gridlocked areas.
Not to worry though, if you're one of the Games partners, i.e McDonald's executives, then you will have the freedom of routes.
