I'm delighted to say that the campaign has been a success and TfL are planning to start work on the crossings in Spring 2020.

TfL say:-

"... we have decided to progress the project...  subject to obtaining the relevant approvals and co-ordinating with other works in the local area, we plan to start construction in Spring 2020."

VICTORY!

Many thanks for the support and looking forward to (finally) being able to cross the road safely in 2020.
