This sign was left on the South Circular, in Sheen, just here.
It asks you to report any problems with roadworks directly to TfL. And they’ve nicely placed it across over half of the not fabulously wide pavement. Just behind the sign, the pavement gets narrower, too.
When you go to visit the site (www.tfl.gov.uk/roadworks) you end up here. It’s not a mistake that the site is for ‘road users’, or it’s about reporting roadworks – if you follow through to the form, there at the bottom, after “untidy site” and site unattended is the option the should probably be used most often: “disrupting traffic or pedestrians”.
