National Highways Safety Alerts
Safety alerts highlight incidents that could have serious consequences to National Highways' staff and supply chain.
Current alerts can be found here: https://www.gov.uk/government/publications/highways-agency-safety-alerts.

Smart Motorways Supplementary Technical and Operational Information
This document accompanies IAN 161/15 (Smart Motorways). It gives high-level guidance on the operational elements of smart motorways designed to IAN 161/15. It should be used by everyone responsible for the design or operation of such schemes, including those involved in incident management, maintenance activities and customer and stakeholder communication.
This document accompanies IAN 111/09 (Managed Motorways Implementation Guidance - Hard Shoulder Running). It gives high-level guidance on the operational elements of smart motorways designed to IAN 111/09, and should be used by everyone responsible for the operation of such schemes, including those involved in incident management, maintenance activities and customer and stakeholder communication.
Please note that managed motorways are now known as smart motorways. Although schemes designed to IAN 111/09 are still in operation, IAN 161/15 has replaced it as the current design standard for new smart motorways, therefore IAN 111/09 and its accompanying documents have not been updated to reflect the new terminology.
This describes a generic safe method for setting up and taking down temporary traffic management (TTM) on ALR schemes. It provides a starting point for scheme designers and maintainers in relation to providing a safe method of placing TTM on ALR.
National Safety Control Review Group and Project Safety Control Review Group Remit
This document outlines National Highways Governance for activities that may impact on safety outcomes for the strategic road network.
It clarifies National Highways' requirements for safety governance to manage safety risks arising for all of our activities that have or may have an impact on safety risk, either directly or indirectly, for any of the populations affected by our operation of our motorway and all-purpose trunk roads.
This document defines the remit of the two main groups required to provide that governance: the safety control review group (SCRG) and the national safety control review group (NSCRG). It also sets out the relationship between NSCRG, the chief highway engineer (CHE), the executive health and safety group (EHSG), and the role played by the safety risk requirements team.
Eurocodes comprises the suite of European standards covering structural design of civil engineering works, including bridges.
Eurocodes replaces the UK national standards, which were withdrawn by the British Standards Institution in 2010. They are now the published and maintained structural design standards in the UK.
National Highways now expresses its requirements for the design of new and modification of existing highway structures (including geotechnical works) in terms of Eurocodes.
Telecom Mast Registration Procedure
The Telecom Mast Registration Procedure (PDF 3.78 MB) is available to download here. The guidance outlines the procedure for gaining technical approval to erect a telecom mast on National Highways land, within the highway boundary or where it may fall onto National Highways land.
Revised Guidance for Air Quality Assessments DMRB 11.3.1
The latest DMRB Air Quality Spreadsheet (2.2MB Zip File) Version 1.03c (July 2007) containing carbon emission rates based on new webTAG guidance is available to download as a zip file here.
This guidance is used for air quality assessments of road schemes, multi-modal studies and by local authorities carrying out their second-phase review and assessments. If you have any queries on this guidance please email the project sponsor for highway schemes or Defra's helpdesk (email@example.com) for local authority review and assessment.
If you would like information on any future changes to the spreadsheet, please contact us via our feedback page.
Road Restraint Systems Further Technical Information
List of EN1317 Compliant Road Restraint Systems
The list of EN1317 Compliant Road Restraint Systems provides details of products that have been certified by a notified body as being compliant with European Standard EN 1317, such as safety barriers, parapets and crash cushions.
Road Restraints Risk Assessment Process
The Road Restraints Risk Assessment Process is part of the Road Restraints Standard CD377 and enables designers to decide whether they need a vehicle restraint at each specific site, and its performance requirements.
Median Safety Barriers on dual carriageways
Median Safety Barriers on dual carriageways describes a study to examine the performance and cost-effectiveness of median safety barriers installed on major roads on the UK network.
Travel of Errant Vehicle Report
Travel of Errant Vehicle Report describes how and where errant vehicles travel after leaving the carriageway. The research has focused on the factors that influence the travel of the errant vehicles, the relative significance of these factors, and potential ways to address them.
