The Network Model digitally represents England’s Strategic Road Network. The model contains critical information about our road’s location, names, lanes and widths.The Network Model was derived from Ordnance Survey (OS) Highways data and enriched with internal datasets. It reflects National Highways roads that are open for traffic and have been validated against our Operational Highway Boundary (RedLine).To ensure the model remains accurate, we have implemented processes to track changes across the network. However, if you have noticed any inaccuracies in the data, please report it here. This form is to be used to report data issues only.In this initial release, speed limit and smart motorway information has been removed pending data validation.To download a file geodatabase containing all layers of the network model and their relationships please use this link.For more information about the Network Model please visit our landing page and technical hub.For maintenance issues on the network please report here. For non-emergency incidents please contact our Customer Contact Centre on 0300 123 5000.The data is published under an Open Government Licence.

This dataset is refreshed on a weekly basis from the datasets the team works on daily.Last update date: 11 July 2025.National Highways Operational Highway Boundary (RedLine) maps out the land belonging to the highway for the whole Strategic Road Network (SRN). It comprises two layers; one being the an outline and another showing the registration status / category of land of land that makes up the boundary. Due to the process involved in creating junctions with local highway authority (LHA) roads, land in this dataset may represent LHA highway (owned by National Highways but the responsibility of the LHA to maintain). Surplus land or land held for future projects does not form part of this dataset.The highway boundary is derived from:Ordnance Survey Mastermap Topography,HM Land Registry National Polygon Service (National Highway titles only), andplots researched and digitised during the course of the RedLine Boundary Project.The boundary is split into categories describing the decisions made for particular plots of land. These categories are as follows:Auto-RedLine category is for plots created from an automated process using Ordnance Survey MasterMap Topography as a base. Land is not registered under National Highways' name. For example, but not limited to, unregistered ‘ancient’ highway vested in Highways England, or bridge carrying highways over a rail line.NH Title within RedLine category is for plots created from Land Registry Cadastral parcels whose proprietor is National Highways or a predecessor. Land in this category is within the highway boundary (audited) or meets a certain threshold by the algorithm.NH Title outside RedLine category is for plots created in the same way as above but these areas are thought to be outside the highway boundary. Where the Confidence is Low, land in this category is yet to be audited. Where the Confidence is High, land in this category has been reviewed and audited as outside our operational boundary.National Highways (Technician) Data category is for plots created by National Highways, digitised land parcels relating to highway land that is not registered, not yet registered or un-registerable.Road in Tunnel category, created using tunnel outlines from Ordnance Survey MasterMap Topography data. These represent tunnels on Highways England’s network. Land is not registered under National Highways' name, but land above the tunnel may be in National Highways’ title. Please refer to the definitive land ownership records held at HM Land Registry.The process attribute details how the decision was made for the particular plot of land. These are as follows:Automated category denotes data produced by an automated process. These areas are yet to be audited by the company.Audited category denotes data that has been audited by the company.Technician Data (Awaiting Audit) category denotes data that was created by National Highways but is yet to be audited and confirmed as final.The confidence attribute details how confident you can be in the decision. This attribute is derived from both the decisions made during the building of the underlying automated dataset as well as whether the section has been researched and/or audited by National Highways staff. These are as follows:High category denotes land that has a high probability of being within the RedLine boundary. These areas typically are audited or are features that are close to or on the highway.Moderate category denotes land that is likely to be within the highway boundary but is subject to change once the area has been audited.Low category denotes land that is less likely to be within the highway boundary. These plots typically represent Highways England registered land that the automated process has marked as outside the highway boundary.Please note that this dataset is indicative only. For queries about this dataset please contact the GIS and Research Team.

DescriptionThe Highway key is a label from OpenStreetMap which aims to map and document any kind of road, street or path. More information on the tag here. LimitationsBear in mind that OpenStreetMap (OSM) is a digital map database of the world built through crowdsourced volunteered geographic information (VGI). Therefore, there is no systematic quality check performed on the data, and the detail, precision and accuracy varies across space. AttributesOBJECTID: Assigned by WWF.

Compiled from forest road network data managed by Forestry Civil Engineering. The data relates to forest road classification.. Last updated from Forester Web on 13/12/2024Forest Roads are categorised on the basis of intended usage (as listed below) rather than the specification used in their construction or upgrading. This can mean that, at a particular point in time, a Class A main road or a Class B spur road may have specification features that could limit its use. Class A - Main Roads " Principal timber haulage route on a long-term basis." Constructed to high specification." Maintained to a high standard." Limiting features shown on road map." All year but not all weather.Class B - Spur Roads" Used by timber haulage lorries for specific operations." Full geometric and safety standards for stated use." Specification tailored to suit purpose." Possibility that surfacing not high quality or durable." Long term maintenance minimal." Each usage subject to individual engineering assessment." Limiting features noted for each particular contract.Class C - Other Roads " Roads other than Main or Spur roads." Maintenance dependent on usage." Not normally used by timber haulage lorries." Use by timber haulage lorries subject to the same individual engineering assessment as Class B roads.

On the Strategic Road Network (SRN) for 2020, the average delay is estimated to be 6.7 seconds per vehicle per mile compared to speed limits travel times, a 29.5% decrease compared to 2019.

The average speed is estimated to be 61.8mph, 5.1% up on 2019.

In 2020, on average 42.1% of additional time was needed compared to speed limits travel times, on individual road sections of the SRN to ensure on time arrival. This is down 25.2 percentage points compared to 2019, so on average a lower proportion of additional time is required.

On local ‘A’ roads for 2020, the average delay is estimated to be 33.9 seconds per vehicle per mile compared to free flow travel times. This is a decrease of 22.8% on 2019.

The average speed is estimated to be 27.3 mph. This is an increase of 8.2% on 2019.

The outbreak of coronavirus (COVID-19) has had a marked impact on everyday life, including on congestion on the road network. As these data are affected by the coronavirus pandemic in the UK, caution should be taken when interpreting these statistics and comparing them with previous time periods. While values had previously been moving towards their pre-lockdown levels, this trend appears to have reversed in the months following September 2020.

These layers digitally represent diversion routes used to manage traffic in response to road closures required across England's Strategic Road Network unplanned events.As part of National Highways' commitment to sharing data, the diversion routes data provides information to help ensure road users are better informed, particularly freight customers, which is why we are communicating the suitability of diversion routes for different vehicles as per customer service standards GG 903 - Customer service standard for diversion routes for unplanned events and GG 907 - Customer service standard for diversion routes for planned works and activities.The dataset consists of the following:Diversion Route: Contains all the diversion routes, and their applicability for different vehicles and link to the closed stretch of the Strategic Road Network that would trigger the diversion route to be implementedSRN Closed Stretch: Contains information about sections of the Strategic Road Network that when closed will lead to a diversion being implementedDiversion Point: Contains all the restrictions along the diversion route, such as height and width restrictions due to low bridges or narrow lanesTo ensure this information remain accurate, the dataset pulls from layers linked to those maintained by National Highways Resilience Planners.For any issues/queries related to the data, please contact: digitallaboperations@nationalhighways.co.ukFor all other issues/queries please contact: GIS@nationalhighways.co.ukThe data is published under an Open Government Licence.

The data show the estimated number of people affected by noise from road traffic, railway and industrial sources, based on an annual average 24 hour period for the situation in 2011. The information arose from the strategic noise mapping undertaken to meet the requirements of Directive 2002/49/EC (the Environmental Noise Directive (END)) and the corresponding regulations.

The information is given for each agglomeration covered by the END and for the major road and railway sources outside agglomerations as defined in the END. Other notes:

• There is no requirement to map industrial sources outside agglomerations.

• Not all agglomerations have industrial sources covered by the END that cause population to be exposed to noise levels in the ranges shown

• The noise exposure ranges shown reflect the requirements of the END

• The END is not prescriptive over exactly what noise sources have to be included in the strategic noise mapping.

• For all agglomerations, the road noise mapping was based on Motorways and A roads only, using data compiled by the Department for Transport.

• For all agglomerations, the railway noise mapping was based on the standard passenger and freight network only.

• For industry, only those sites which met the definition of a Part A(1) activity as described in the Environmental Permitting (England and Wales) Regulations 2010 were included.

SpeedMap is a project with the aim of producing a national speed limit database for the UK and Republic of Ireland which can be used with any digital map. Ten years ago we recognised the need for an accurate map to support innovation in road safety – without being tied to a costly proprietary mapping solution. Our data is sourced from a multitude of datasets and boasts 100% coverage of the UK and RoI road network with industry-leading accuracy >99%. Since supplying the first version to a telematics startup in 2012, SpeedMap has become the number one choice for companies who need speed limit data. Our dataset is used by global mapping providers, delivery companies, utility providers, insurance companies, as well as those providing in-vehicle systems. We make our data accessible, reliable and exploitable for your commercial needs, as well as putting the data in the hands of those responsible for making our roads safer.

Thanks to OS MasterMap Highways Network with Speed Data, you can also access road speed information through our product. It’s an additional dataset to help you plan logistics and monitor our roads more effectively.

Perhaps you're looking for more data about Great Britain's roads? Or maybe you're studying drive times or comparing vehicle types along routes or the impact of a new development? This could be the product for you.

We have enhanced our Highways Network family of products with these three speed data additions. Each product is supplied with an additional data file which will be either Average Speed, Speed Limits or a combination of both.
