Barriers to remain on Thames bridges for 'foreseeable future'

The barriers – which the Mayor recently described as a "temporary measure" – were installed in the days after the London Bridge terrorist attack.

Answering questions from London Assembly members, Mr Khan said: "Hostile vehicle mitigation (HVM) has been installed on the eight bridges in central London: Blackfriars, Lambeth, London, Tower, Southwark, Vauxhall, Waterloo and Westminster.

"Current deployments will remain in place for the foreseeable future and authorities are considering suitable longer term solutions."

In another response he said: "I recognise that the barriers the [police] have installed to increase security have affected cyclists and pedestrians who use London's bridges.

"The Walking and Cycling Commissioner, Dr Will Norman, is working with TfL, the MPS and local councils, among others, to deliver short-term improvements that maintain the safety and security of all road users, as well as longer-term solutions."

In a further answer to a similar question the Mayor said: "The relevant authorities have discussed the security measures currently in place and the initial issues faced by cyclists on Blackfriars Bridge have now been resolved.

"It is recognised by all involved that a more permeable option must be agreed. There will be further consideration of security measures and any action taken will need to maximise the safety of pedestrians and road users.

"Work is under way to identify longer term security solutions which will be based on relevant advice from the Home Office."
