The Mayor of London Sadiq Khan has expressed his commitment to expand the Ultra Low Emission Zone (ULEZ) this year to make London’s air cleaner and improve public health. Transport for London (TfL) is planning to expand ULEZ across all London boroughs from 29 August 2023.

Imperial confusion on new tunnel signs
Transport for London (TfL) was today criticised by the UK Metric Association (UKMA) for bungling the erection of new signs at the Rotherhithe tunnel, including banning all vehicles over 33 inches long from using the tunnel – and for wasting up to £6000 on erecting or amending new signs that will soon be obsolete.
