The London Streets roundel.
London Streets (known as Street Management until April 2007) is an arm of Transport for London (TfL) which is responsible for managing the main through-routes in London, a total network of 580 kilometres (360 mi) of roads. These are also known as red routes, or the Transport for London Road Network (TLRN), as they can be identified by their red road markings and signage.
London Streets is also responsible for managing the London congestion charge, a fee that is charged to most motorists entering the central London area, as well as street CCTV systems and control of traffic lights and bus lane enforcement cameras (BLECs).
Motorways within London are the responsibility of the Highways Agency. The remainder of the city's street network is the responsibility of the individual London boroughs.
