He said the Northern Distributor Road and the Cross-Valley Link Road were vitally important to the future of the town.
'In linking the town centre directly to the M4, the roads will open up considerable opportunities for development, providing scope for more jobs, better housing, highly sought after retail outlets and improved transport,' he said.
Mr Griffiths said the BAA McArthur Glen Designer Outlet Village was due to open next month at Sarn, where the existing retail park, occupied by J.Sainsbury, had been extended. He was confident this development would generate many other trade opportunities, for which the new distributor road would cater.
'The opportunities for north Bridgend are tremendous,' he said, 'and what we have here is a prime example of how public authorities and the private sector can work together to achieve so many benefits for the area.'
Mr Griffiths congratulated Bridgend Council on the schemes - completed ahead of schedule and more or less to budget.
Paying tribute to the co-operation which has enabled the public sector partnership between the Land Authority and Bridgend CBC to work so effectively with the private sector - J Sainsbury and BAA McArthur Glen in particular, he said: 'What this scheme has achieved is a clear beacon for local authorities and other public sector bodies to extend the same spirit of partnership with the private sector for the benefit of local people.'
Bridgend CBC's£29m Bridgend Cross-Valley Link Road scheme is being supported by the Welsh Office under the Transport Grant arrangements. Grant is payable at 50 per cent of eligible expenditure with the balance made up with supplementary credit approval.
The Bridgend Northern Distributor Road has been funded mainly through the Land Authority for Wales, with a Transport Grant contribution through Bridgend CBC.
