Our ref: FOI-0883-1718/GH
Thank you for your request received by Transport for London (TfL) on 11 July 2017 asking for further information about Pavement Gritting on the TfL Red Route Network.
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.
Please find attached a higher resolution copy of the map showing the footway hierarchy for the transport for London Road Network. I also attached a more detailed map of Westminster Bridge which I hope you will also find useful.
Like most Highway Authorities in the UK, TfL do not have a set intervention level (temperature) at which we would treat footways. Our decision is based on guidance provided in Well Maintained Highways taking into account local weather conditions and the budget available.
I can confirm that TfL is the Highway Authority responsible for Westminster Bridge.
If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.
