The detailed approach to Structures is outlined in the lifecycle plan. Structures require a variety of treatments dependant on the nature of the deterioration which can vary from the occasional full replacement of a bridge through to individual bridge schemes to refurbishing waterproofing and/or parapets to both address the short term issues and to minimise whole life costs.
A 15 year programme has been built up from the program of inspections carried out on the existing stock. The programme will be updated and amended following the cyclic principal bridge inspections if more advanced deterioration is identified.
This programme has started to be delivered (from 2014) by our service provider in conjunction with Milton Keynes Investing an additional £50 million in its highway network asset.
