296Wimprovement to provide noise barriers alongside trunk roads and motorways which were opened to traffic on or before 16 October 1969, and have not been subject to further improvement.
Subject to the availability of funds, noise barriers may be provided on such unimproved roads open to traffic on, or before, 16 October 1969 where the cost does not exceed the notional cost of insulating properties which would have qualified had the 1975 regulations applied on 16 October 1969. For these purposes qualifying properties are those which existed on 16 October 1969. The calculation of noise impact is to be based upon the assessed traffic flows at 16 October 1984. It must also be technically possible to provide effective barriers alongside the road.
This ensures equitable treatment, with respect to noise barriers, between residents living near to roads opened before and after 16 October 1969.
