Is it the Mayor or Transport for London pushing through flawed Blackfriars plans?

Transport for London is ignoring the London Assembly's all-party call for a review of Blackfriars Bridge and a retention of the 20mph speed limit.

TfL has issued a press release saying that it will start works on the bridge this Friday, 31 July 2011, despite the fact that at Mayor's Questions on Wednesday 13 July 2011, Boris Johnson said:

“More work needs to be done on cycling over Blackfriars Bridge and over the accessibility of cycling over Blackfriars Bridge. And speaking as someone who uses that route the whole time I am very much familiar with the problems of the cyclist on Blackfriars Bridge and I am working with TfL to try to work it out.”

LCC's Mike Cavenett said, "Cyclists deserve an explanation from the Mayor. Is he working with Transport for London as he said he would or not?"

Mayoral candidate Jenny Jones has no doubt who's responsible: "This is a dreadful decision by the Mayor and TfL, and flies in the face of all the public support for a safer bridge. The Mayor isn't listening to London."

On 20 July 2011 the London Assembly unanimously backed a motion on Blackfriars which asks the Mayor to carry out a review of the speed limit on the bridge and revisits the plans for the bridge "with particular attention to cyclists making right turns when exiting the bridge at either end".
