FOI request detail

Pavement Gritting of Red Route Network

Request ID: FOI-0659-1718
Date published: 10 July 2017

You asked

I want to know what is TfL's policy and/or the criteria that TfL apply in determining WHICH pavements on the TfL Red Route Network are gritted and WHEN (e.g. under what specific weather conditions such as ambient temperature). Can you provide a map or list detailing all of the pavements on the Red Route Network that have been identified as those that should under certain weather conditions, be gritted. Can you confirm that TfL is the Highways Authority for Westminster Bridge? Westminster City Council have informed me that TfL are the Highways Authority for Westminster Bridge. What risk assessments (if any) or other studies have been carried out by TfL to determine whether and under what specific circumstances, the pavements on Westminster Bridge require gritting/salt spreading measures.

Thank you for your request received by Transport for London (TfL) on 13 June 2017 asking for information about gritting pavements.


Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold some of the information you require.


We grit our footways in accordance with the following prioritisation :-


Prestige (within 4hr of instruction), Primary (within 4hr of instruction) , Secondary & link footways (within 24hr of instruction) or local access (within 48hr of instruction). The decision to grit is dependent on forecasted weather conditions and the category of footway. The treatment can be pre-cautionary i.e. before the formation of snow and ice, or after snow and ice have formed. TfL follows the guidance provided in ‘Well Maintained Highways’. Westminster Bridge is classified as ‘Prestige’.


I attach a PDF file showing pan-London TLRN Footway Hierarchy.
