 The former chairman of the South Glamorgan County Council environment committee , Councillor Paddy <unk> , called the road a " necklace of opportunity " due to its shape and also the opportunities for regeneration . By 1 April 1996 the responsibility for the road was transferred from South Glamorgan County Council to the unitary authority of Cardiff Council . Much of the funding for the road had been grant aided from the European Community and the UK Government on the basis that it would improve the economic viability of the area and bring in new jobs and industry . However , since the completion of the Butetown Link Road , funding for further developments have been at a stand still , and to date 22 kilometres ( 14 mi ) including spurs are open to traffic with plans for a further 5 @.@ 53 km ( 3 @.@ 44 mi ) . The " missing link " , the Eastern Bay Link Road , is still to be built .
