Highways infrastructure asset management

Highways infrastructure assets are the elements that make up the highway such as roads, pavements, drains, bridges and street lights and road signs.


Comment on our asset management strategy and policy

Asset management is about understanding these assets then using the information we hold about them to prioritise how we look after them in a cost effective way.

The emphasis is on managing our infrastructure assets efficiently and effectively by focusing on investing in long-term planned maintenance instead of short term repairs.

It is about making best use of available resources to keep our highways in a condition that makes them safe and reliable for all users throughout their lifecycle. For example, it may mean a road is patched rather than resurfaced but in the order of importance it is still fit for purpose for its level of use.

Asset management is about using data to manage risk and keep Derbyshire on the move to support the economic, social and environmental well-being of the county.

How we manage this data is described in our data management strategy, which is attached to this page.

To manage our assets we need to know:

  • the type of asset
  • where it is located
  • why it is at this site and its value within the road network
  • when it needs to be inspected, maintained or replaced
  • how long it will last and how much it will cost to replace or repair throughout its lifecycle
  • who is responsible for looking after and repairing it

A key element of effective highways infrastructure asset management is long term planning. On 18 April 2019, Cabinet approved a 5 year indicative forward works programme - see agenda item 14.

Priority roads

The resilient network is the name given to roads we give priority to protecting in adverse conditions. Usually this is extreme weather – snow, ice and flooding – but it may also include events like industrial action and major incidents. Around 10% of the 3,335 miles of road we manage fall into this category.

Assets

We are currently responsible for:

  • 299 miles on the resilient network, 3,036 miles on the non-resilient network – 3,335 miles in total
  • 201 miles of cycle ways and greenways - traffic-free paths suitable for walking, cycling and horse riding
  • in excess of 2,796 miles of pavements and 3,093 miles of public rights of way
  • 1,182 road bridges, other bridges and boardwalks, plus approximately 1,000 footbridges
  • around 610 miles of retaining walls
  • approximately 89,650 street lighting columns
  • 129 signalised junctions
  • 21 pelican, 255 puffin, 21 toucan and 7 equestrian crossings
  • 166 permanent and 66 mobile warning signs and 604 flashing amber warning lights
  • roadside drainage including 165,577 gullies
  • 2,407 sites with pedestrian barriers
  • 76,984 traffic signs
  • 69 miles of crash barriers
  • cutting back roadside trees and verges

Our highways infrastructure asset management policy and strategy documents are attached to this page. They set out how we will deliver road-related services against our key priorities. They take into consideration residents' needs, the condition of the asset and how best use can be made of available resources.
