Details of associated bus diversion are on the TfL website.

Is anyone else a little p****d off at this? Whilst trying to attract
more people to Oxford Street and Regent Street, they are diverting the
buses away, thus making it more difficult to get there, and
conseuqently making the tube more overcrowded than it already is.

I am just wondering whether the benefits of making Oxford Street car
free outweigh the disadvantages
