Red routes and traffic lights
We do not maintain red routes. They have single red or double red lines on them and are normally A roads, designated as A217, or A24 etc. These roads, signs, markings and lighting are maintained by Transport for London (TfL).
We do not maintain traffic lights either. All traffic lights are the responsibility of TFL.
If the fault is on a red route you can report it at https://reportit.tfl.gov.uk
