§ Baroness Miller of Chilthorne Domerasked Her Majesty's Government:
What United Kingdom standards are applied by the Department for Transport to road bridge expansion joints with regard to noise generated by road traffic crossing the structure; and whether these standards have changed since 1984. [HL3149]
§ Lord Davies of OldhamThe standard used by the Highways Agency for the design of road bridge expansion joints on the motorway and trunk road network in England is "BD33/94—Expansion Joints for Use in Highway Bridge Decks" published in 1994. The current standard, and earlier versions, has no requirements covering noise generated by road traffic crossing over bridge expansion joints. The correct installation and maintenance of bridge expansion joints helps to minimise the noise generated by road traffic crossing over them.
