Thank you for your request received by Transport for London (TfL) on 4 November 2024 asking for information about the A20 (Sidcup bypass) Temp 40mph Order 0622.

 

Your request has been considered under the requirements of the Environmental Information Regulations and our information access policy. 

 

You are referring to Chapter 8 of the Traffic Signs Manual – Traffic Safety Measures and Signs for Road Works and Temporary Situations. The A20 scheme you are referring to was not a temporary situation. Chapter 3 rather than Chapter 8 applies, and this guidance was adhered to – maintaining an overall effect of the signs to provide adequate guidance to drivers of the speed limit. Therefore we do not hold the information you have requested. 

 

Please see the attached information sheet for details of your right to appeal.

 

Yours sincerely

 

Graham Hurt
