Highway Infrastructure Asset Management Plan

A Highway Infrastructure Asset Management Plan (HIAMP) is a document that helps inform investment decisions to help maintain our transport network. 

Our HIAMP was updated in February 2016 to reflect the recommendations in guidance published by the Highways Maintenance Efficiency Programme and the new ‘Well-Managed Highway Infrastructure Code of Practice’ published by the UK Roads Liaison Group. 

The Plan is particularly important because our current funding levels are not enough to keep all our transport assets in ‘as new’ condition. Transport assets include carriageways, footways and cycleways, highway structures and bridges, street lighting, street furniture and signs and highway land. 

The HIAMP sets out what assets we have, what condition they’re in, and what we are likely to need in the future. This allows us to direct our limited funds effectively by applying the principle of ‘right maintenance treatment at the right time’ to minimise whole life costs.

Transport Asset Management

The highway authority is an organisation that is responsible for the management of the public highway. This role can be held by a number of different groups.

In Hull the council is responsible for managing all adopted local roads with the exception of the A63 which is the responsibility of Highway England.

In its role as the highway authority the council maintains a large network of assets to support the public’s highway rights. These assets include:

  • 730km (454 miles) of carriageway
  • 1,100km (684 miles) of footways
  • 284 bridges and structures
  • 33,000 street lights
  • 2,600 illuminated traffic signs
  • 77318 gullies


The value of all the council’s highway assets is just under £2billion.

The long term strategy for highways is set out in the Highway Infrastructure Asset Management Plan (HIAMP) and was adopted in February 2016.

The investment in maintaining the existing road network is directed to where it makes the most significant impact in terms of achieving the council’s corporate priorities and objectives.

This means ensuring that all strategic routes are maintained to a good condition to ensure the movement of goods, services and personnel across the city, whilst also providing a level of funding for residential roads within local communities.

Current funding is unfortunately not enough to maintain the whole network to an appropriate level, resulting in a number of unclassified roads deteriorating to a level that is lower than the authority would have hoped, before treatment can be undertaken.

The existing road network is subject to constant wear and tear from ever increasing volumes of traffic and the unpredictable adverse weather conditions experienced in this country. For the Council to bring the entirety of its existing highway network up to an ‘as new’ standard, the required cost is estimated at around £62million. This is also referred to as the maintenance backlog.  It is also estimated that each year the carriageway network would require nearly £7million to be spent on maintenance in order for the back log to remain at its current level. Due to the shortfall in funding there is currently not enough money to fund all the maintenance schemes we would like and we therefore have to accept there always be roads that are not in the best condition. Due to this shortfall, we have to prioritise our planned maintenance work carefully to ensure the maintenance we do carryout offers the best value for money and the maximum benefit for the city’s residents and visitors.

To make the most out of the existing network infrastructure we carry out 2 different types of preventative treatments on our carriageways, surface dressing which is historically done on the classified road network and micro surfacing which is historically done on the unclassified network and in particular on residential roads. Using these preventative treatments enables us to treat a far greater area of carriageway than would otherwise be possible. Some sections of the existing carriageway network have already deteriorated to a point where these treatments are not a viable option and therefore cannot be used. These sections of carriageway are therefore considered for a more substantial and more expensive planned, major resurfacing or reconstruction scheme.

Our planned major work is currently programmed over a 3 year time frame. The programme is reviewed on an annual basis using information that has been gathered for every adopted carriageway and footway throughout the city and is updated or altered when necessary. The data amassed each year includes condition surveys carried out by accredited external contractors, inspection data and reports collated by the councils own internal inspection team, resident and visitor enquiries that are raised through the councils call centre or via area/ward requests. Priority lists are then produced on the basis of this information whilst also taking into account factors such as traffic counts and usage of each individual location to make the best use of our available funding.

The annual capital funding allocation that Hull City Council currently receives form the Department of transport is split between the different treatments and locations using an asset management based approach, taking into account the Performance Indicators (PIs) that are annually reported.
