asked Her Majesty's Government:
What was the cost of upgrading highways and bridges to accommodate the last increase on maximum lorry weights to 44 tonnes.
Six-axle 44-tonne lorries have been authorised on UK roads since
Both the Highways Agency and local highway authorities undertake considerable investment in their networks, but it is not possible to identify how much of this was specifically to accommodate 44-tonne vehicles. When the EU directive came into force, all bridges on the motorway and trunk road network were able to accommodate 40-tonne vehicles. Maintenance of other roads is a matter for the relevant local highway authority.
