No special assessment has been made of the effect of the extreme weather incurred during 2008-09 on the condition of the network. However, the Highways Agency carries out regular network condition surveys and timely safety inspections to ensure appropriate funds are allocated to maintain the network in a safe and serviceable condition. The Highways Agency's experience is that road defects due to extreme weather are likely to be safety related, which are treated promptly as part of the routine and winter maintenance programme. Costs for treating such defects are small and are managed using the overall allocated maintenance expenditure.
