A lot of people are coming to this site searching for information about temporary travel during the Olympics, especially on roads.
The Get Ahead of the Games website has an area where you can put in your postcode and check the impact for driving, cycling, pedestrians and public transport:
The main road impact for Leytonstone is that the A12 (M11 link road) has a Games Lane right down to and including the Blackwall Tunnel and A13, the roads around Stratford town centre, the new road north of the Olympic village, Temple Mills Lane, Ruckholt Road, and parts of High Road Leyton are all affected. As well as Games Lanes, some roads will be subject to closure. For example, there’s no entry to the A12 from the Green Man Roundabout from 23 July, operating from 0600-1100 each day until 14 August, then again for the Paralympic Games between 27 August until 11 September.
If you are leaving the M11, the Wanstead/Redbridge roundabout exit is affected but the London NE/Walthamstow exit does not appear to be.
The Games Lanes are sometimes on the left, sometimes in the middle, sometimes dedicated lanes, and sometimes shared with bus lanes.
Some restrictions are only temporary, so if you find you can drive freely one day, that may not apply at another time: do beware as the fine for using a Games Lane is £130!
There are also lots of other useful links about the Olympics and how they affect Leytonstone on the Olympics 2012 page.
See the bottom of each page on this website for other useful transport links including live feeds from eg the Highways Agency.
