Despite the common law maxim, 'once a highway, always a highway', a highway can be subject to overriding statute. Consequently, highways may be closed or diverted under many Acts of Parliament, or by natural causes. For diversion and closure of highways by natural causes, see Practice Note: Natural and other causes of diversion and closure [Archived]. Stopping-up of highways The two most frequently used powers to stop up a highway are in section 116 of the Highways Act 1980 (HiA 1980) and section 247 of the Town and Country Planning Act 1990 (TCPA 1990). The government guidance ‘Apply to close or divert a highway’, published on 25 March 2025, provides a form for stopping-up orders under TCPA 1990, ss 247, 248 or 253. Under HiA 1980, s 116, the highway authority may apply to a magistrates’ court for a stopping-up order. The only ground for such an order is that the highway is unnecessary. Under HiA 1980, s 117, any person who wants a highway stopped up as being unnecessary may ask the local highway authority
