Highway Asset Management

Highways Asset Management Framework

Our Highways Asset Management Framework aims to assist the council in creating a safe, reliable and accessible transportation system which supports development of a strong low carbon economy, maximising the opportunities for sustainable transport and protecting the environment.

Like most highway authorities, the condition of our carriageways and footways had become worse.  This framework sets out how an asset management approach has helped, with early investment, to improve the condition of our highway infrastructure and reduce maintenance backlogs.

The framework was formally adopted in 2015 and asset management now plays a key role in helping us maintain and manage our highways.

What is asset management and why do we need it?

Asset management is a systematic process of maintaining, developing or upgrading assets (for highways this is our roads, structures, signs). It takes a structured approach to inspections, maintenance programmes and requirements for new assets and allows us to look at all transport issues collectively so we can plan for the future.

The framework sets out exactly how many highway assets we are responsible for:


Size of Asset Equivalent
Carriageway 1533 km (958 miles) Yate to Rome
Footway 1391 km (864 miles) Bristol to Palma
Cycle routes  118 km (73 miles) Warmley to Stratford-upon-Avon
Public Rights of Way 1,265 km (786 miles) Almondsbury to Innsbruck
Traffic Signals 

74 Junctions

127 Crossings

Fairy lights stretching 2 km

1 km of zebra stripes on the road



Connecting Pipes

Main Pipes


45,000 Gulleys

135 km (86 miles)

171 km (106 miles)


3.2 Olympic pools of water

Winterbourne to Slough

Patchway to Plymouth



Retaining Walls

788 Bridges with total deck surface area of 47,500m2 7 football pitches
341 Highway retaining walls with total length of 15 km Yate to Kingswood
Street Lighting

29,500 Units

(5,888 tonnes CO2)

Lighting for 128,000 homes
Grass Verges 2.9 million m2 425 football pitches

In South Gloucestershire, more than 2.316 billion vehicle miles are driven each year and with traffic predicted to grow annually by 1.4%, we need to protect our assets from wear and tear and help support the economy.

Using asset management for our highways also allows us to access different funding and so far we have been very successful in bidding for central Government grants to improve our assets eg £21 million Challenge Fund for the A403 and A4174 including the Bromley Heath Viaduct.


Hierarchy is splitting our network into levels based on use. At present we use A, B, C and Unclassified to categorise our roads but this means we have the same standards for minor rural tracks as we do for well used roads in our urban area and a rural A road is treated the same as the A4174 or A38.

Hierarchy enables us to set differing levels of service to manage these different roads to more appropriate standards.
