The GLA Roads (Supplementary Provisions) Order 2000
This Order provides that section 14A of the Highways Act 1980, as inserted by section 260 of the Greater London Authority Act 1999, is to have effect so that roads in Greater London, to which the public has access, which are not highways and which were built by an urban development corporation, may be designated by the Secretary of State as GLA roads and become highways maintainable at the public expense.
