It is not correct to imply that safety barriers on our roads are inadequate or that NRA standards or practices constitute a contravention of EU standard EN 1317. I understand from the NRA that, since January 2002, all road improvement contracts involving the provision of safety barriers are tendered exclusively on the basis of the EU standard EN 1317 for safety barriers.
The proceedings to which the Deputy refers related to compliance with EU procurement directives which require that EU product standards, where available, be used exclusively in tender invitations. Prior to January 2002, the NRA had been specifying both the EU standard and a comparable British standard. Following contacts between the Commission, my Department and the NRA, the authority changed its practice in January 2002 to refer exclusively to EN 1317 in tender invitations.
The EN 1317 standard has been adopted by the EU under the construction products directive as part of the EU process of harmonising product standards. It is a performance standard which sets out the testing requirements for different classes of barriers. It does not specify whether or when safety barriers are to be provided. That is a matter for national authorities. The application of EN 1317 does not call into question the adequacy of barriers procured and installed under the arrangements in place prior to January 2002. The barriers concerned comply with best international practice and provide the same level of safety as barriers supplied and installed in response to tenders based on exclusive use of the EN 1317 standard.
The position on providing median barriers on motorways and dual carriageways is that the NRA's current standards provide for high containment safety barriers in central medians up to 7.5 metres in width and normal containment safety barriers in central medians greater than 7.5 metres in width but not exceeding 15 metres in width. Where median width is greater than 15 metres, the median itself provides the safety mechanism. The NRA has been asked to consider further the position on the retrofitting of safety barriers on existing motorways and dual carriageways where the central reservation is greater than 15 metres.
