The Ghana Highway Authority was established as a body corporate under NRC Decree 298 in December 1974. The NRCD 298 was repealed by GHA Act 1997 (Act 540 ) which limited the Authority's responsibility to the administration, control, development and maintenance of the country's trunk road network totalling 15,000 km and related facilities in Ghana. Its mission is to provide Road Infrastructure Engineering and Management Services at best value – least cost to support the socio-economic development of Ghana and beyond.
