This coloured street map of the Extended London Congestion Charging Zone highlights separately the existing charging zone area and the extended area. The western extension to the congestion charge zone is expected to come into force on 19th February 2007. The map's coverage extends beyond the combined zones' area to include Willesden Green, Primrose Hill, Highbury & Islington Station, Bethnal Green Station, Rotherhythe Station, Camberwell Green Junction, Fulham Palace, Hammersmith Flyover and Savoy Circus Junction. Postcode districts are featured on the mapping. On the back cover is a Central London Underground Map. The index is printed on the reverse of the map and includes streets, selected flats, walkways and places of interest, junction, place and area names, hospitals and hospices, National Rail, London Underground and Docklands Light Railway station names. Streets that are within the current and extended charging zones are highlighted with separate charging zone symbols.
