Design Manual for Roads and Bridges and Manual of Contract Documents - Forward Look

This page lists the current status of Design Manual and Manual of Contract Documents which have been submitted for publication.

Managed Motorways Supplementary technical and operational Information

(PDF, Opens new window) Managed Motorways - All lanes running - Concept of operations

This document is an Informative Reference to Interim Advice Note (IAN) 161/12 Managed Motorway Requirements - All Lane Running. It gives, at a high level, guidance for the operational elements of managed motorways designed to IAN 161/12. This document should be referred to by all those who will be responsible for either the design or operation of managed motorway schemes, including those involved in incident management, maintenance activities and with customer and stakeholder communication.

Managed Motorways - Dynamic Hard Shoulder (MM-DHS) Concept of Operations

(PDF, Opens new window) Managed Motorways - Dynamic Hard Shoulder (MM-DHS) Concept of Operations

This document is an Informative Reference to IAN 111/09 (Managed Motorways Implementation Guidance - Hard Shoulder Running). It gives, at a high level, guidance around the operational elements of managed motorways designed to IAN 111/09. This document should be referred to by all those who will be responsible for either the design or operation of managed motorway schemes, including those involved in incident management, maintenance activities and with customer and stakeholder communication.

Passively Safe Gantry Risk Model (PSGRM)

The Passively Safe Gantry Risk Model has been developed for designers to use to help determine whether or not a passively safe gantry is suitable for a particular site.

Eurocodes

Eurocodes are the suite of European Standards covering structural design of civil engineering works, including bridges.

When the UK National Standards that were in conflict with Eurocodes were withdrawn by the British Standards Institution (BSi) on 31 March 2010, Eurocodes became the published and maintained structural design standards in the UK.

The Highways Agency 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 (PDF, Opens new window) 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 Highways Agency land, within the highway boundary or where they may fall onto Highways Agency land.

Guidance on the siting of Wind Turbines

The Highways Agency is using the following working guidance for criteria for appraising proposals for the construction of wind farms near the Highways Agency network. The guidance outlines the factors that will need to be considered by the Highways Agency and developers when considering proposals for siting of wind turbines near the strategic road network.

Air Quality

Revised Guidance for Air Quality Assessments DMRB 11.3.1

The latest (Opens new window) 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 will be used for air quality assessments of road schemes, multi-modal studies and by local authorities carrying out their second phase review and assessments. Queries relating to this guidance should be addressed to the Project Sponsor for highway schemes or to Defra's helpdesk (lasupport@aeat.co.uk) for local authority review and assessment.

If you would like to be notified of any future changes to the spreadsheet, please send your name, organisation and email address to dmrbaqusers@highways.gsi.gov.uk

Road Restraint Systems Further Technical Information

HA Accepted EN 1317 Compliant Road Restraint Systems

The HA Accepted EN 1317 Compliant Road Restraint Systems list provides details of products such as safety barriers, parapets and crash cushions that have been certified by a Notified Body as being compliant with European Standard EN 1317.

Road Restraints Risk Assessment Process

The Road Restraints Risk Assessment Process is part of the New Road restraints Standard TD19/06 and enables the Designers to determine at each specific site, the need for a Vehicle Restraint and its performance requirements.

Median Safety Barriers on dual carriageways

Details of a study to examine the performance and cost effectiveness of median safety barriers installed on major roads on our network.

Travel of Errant Vehicle Report

This is a report about how and where errant vehicles travel after leaving the carriageway. The research has focussed on the factors that influence the travel of the errant vehicles, the relative significance of these factors, and potential ways to address them.
