Mayor of London Boris Johnson has ruled out making the current temporary 20 mph speed limit on Blackfriars Bridge a permanent measure despite a vigorous campaign by cyclists.
Mr Johnson was questioned at City Hall on Wednesday by Green Party London Assembly member Jenny Jones who put to the Mayor the findings of a 2008 Transport for London report which recommended a 20 mph limit on several Thames bridges.
"My information is that the general speed [on Blackfriars Bridge] is nearer 12 miles an hour, therefore a speed limit of 20 mph isn't necessary and could be a serious impediment to smooth traffic flow," said the Mayor. "I'm not convinced of the case for this."
He added: "I do think more work needs to be done on cycling over Blackfriars Bridge … 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 and sort it out.
Ms Jones pressed the Mayor on why he was ignoring the findings of the report prepared by TfL in 2008. The Mayor replied: "I am told that it does not represent the best advice and therefore I am not pursuing it".
The London Cycling Campaign is among the groups calling for a permanent 20 mph speed limit on the bridge. The LCC organised a go-slow flashride across the bridge in May to highlight the issue.
