The London Cycling Campaign has called on commuters to back a motion to make the temporary 20mph speed limit on Blackfriars Bridge permanent.

The London Assembly is due to vote next Wednesday, June 8, and members from Labour, the Liberal Democrats and the Green Party have, according to the LCC, already indicated they will support the motion, introduced during roadworks on the bridge.

But London Mayor Boris Johnson is under no obligation to follow the motion, even if it is passed, and the LCC has asked cyclists to sign a petition to show their support.

“This Assembly regrets the Mayor’s failure to retain the temporary 20mph speed limit on Blackfriars Bridge in the permanent new scheme for the bridge,” reads the motion.

“We note the recommendation for a 20mph speed limit on four London bridges in a 2008 Transport for London report, and the recent decision of the Corporation of London to ask officers to bring forward plans for the whole of the City of London to become a 20mph zone, including TfL roads.

“We ask the Mayor to reconsider his rejection of a 20mph limit on Blackfriars Bridge, in the interests of the safety of all its users.”

The removal of the temporary speed limit is part of a wider plan on the bridge, but Transport for London has scrapped plans to remove its cycle lane – a key route for commuters into the City of London.

A flash ride took place on the bridge last month, with approximately 300 cyclists staging a go-slow protest.
