As I indicated in my reply to Parliamentary Question No. 27906/03 about EU Commission infringement proceedings relating to the procurement of safety barriers, the position on safety barrier standards is that the NRA's current road design standards provide for high containment safety barriers in central medians up to 7.5m in width; normal containment safety barriers in central medians greater than 7.5m wide but not exceeding 15m in width; and where the median width is greater than 15m no safety barrier is required as the median itself provides the safety mechanism. In addition, all road improvement contracts are tendered exclusively, since January 2002, on the basis of the EU standard, EN 1317, for safety barriers.
