M25 LONDON ORBITAL ROAD. NORTH EAST SECTOR

The paper first traces briefly the evolution and purpose of the government's top priority M25 London Orbital Motorway. It then describes the planning and design of the north-east sector between A1 and the Dartford tunnel. The environmental restrictions which limited the choice of route in encircling the main built-up areas of Greater London and at the same time providing for traffic movements are discussed. The reconciliation of these requirements posed considerable engineering problems and some of the more interesting of them are described. They include the construction of two cut-and-cover tunnels, one in an urban area at Waltham Cross and the other at the north end of Epping Forest. Because of its function and location, the M25 route crosses several radial road and rail arteries converging on the capital. The north-east sector includes the provision of a free flow interchange with M11 and interchanges with trunk and principal roads. The paper describes the interchanges and signing and outlines the arrangements for the monitoring and maintenance of this length of M25. (Author/TRRL)
