HC Deb 10 December 1981 vol 14 c488W
Mr. Banks

asked the Secretary of State for Transport which bridges in north Yorkshire will require strengthening to accommodate lorry weights of 40 tonnes.

Mr. David Howell

No strengthening on account of the heavier lorry weights now proposed by the Government is envisaged for short-span bridges, for example 2–75 metres, which constitute the vast majority of bridges in North Yorkshire. The relatively few bridges with spans greater than about 75 metres will need to be examined individually to see if any strengthening particularly for the heavier lorries is required.
