Title Document type Published Publisher
Well-maintained Highways Tracked Changes Version

Read document description

Since Well-maintained Highways was published in 2005, Government Policy with respect to highway maintenance has developed and evolved in a number of areas. There have also been a number of changes, including the introduction of new statutory duties on highway authorities. To assist users of this Code, the Roads Liaison Group has prepared complementary guidance to advise and direct users to where they may find more up to date information to assist them in implementing best practice and the recommendations of the Code. Users of the Code should treat this complementary guidance as up-to date and having the same status as the Code. Where paragraphs have been amended, they supersede the ones in the Code. It must be noted that these updates should not be read in isolation but should be considered within the context of the Code

Winter Service Guidance: Recommended Precautionary Treatments and Post Treatments Including Revised Salt Spread Rates

Read document description

An independent review (“the Quarmby Review”), commissioned by the previous government and continued by the current Secretary of State for Transport, to consider the resilience of English transport systems, produced a final report in 2010. Its recommendations aim, inter alia, at providing measures to improve local highway authorities‟ preparedness for winter. In particular, the review noted a need for „research which would underpin recommendations for the adoption of lower salt spread rates […] to improve resilience of the salt supply chain‟ (recommendation 23). With the early onset of the 2010/11 winter service season, the need for guidance on appropriate spread rates to reduce salt usage on local roads and improve resilience has become a high priority. The Department for Transport believes that it would be helpful to provide simple spread rate guidance to local authority practitioners as a matter of urgency. This document provides the required guidance.

Planning for SuDS - making it happen

Read document description

Sustainable drainage systems or SuDS are a more natural approach to managing rainfall where it falls. They are an important part of delivering sustainable communities and development, and should be considered together with established requirements for public open space, parking and transport. Planning for SuDS - making it happen is primarily intended for use by those people involved in the planning and development process requiring independent and digestible information on the delivery of SuDS. The guidance provides an easy to use reference for those not overly familiar with SuDS, the planning and development process or a mixture of both, and should be viewed within the wider context of surface water management. This guide will help the planning, design and delivery of attractive and high quality SuDS schemes - efficiently delivered SuDS will unlock other sustainability benefits

Culvert Design and Operation Guide

Read document description

A culvert provides the means of allowing infrastructure to cross a watercourse. Culverts are superficially simple structures, but they have the potential to restrict flow (causing flooding), and to adversely affect the aquatic environment. This guide replaces the Culvert design manual (R168) published by CIRIA in 1997. It adopts a whole-life approach to the design and operation of culverts, with a focus on asset management, reflecting the significant changes that have occurred in the business of asset management over the past 10 to 15 years. The publication also addresses the management of culverts in the context of both the drainage basin in which they sit, and the infrastructure that they form part of. This is a comprehensive guide covering a wide range of subject matter relevant to the design and operation of culverts, but does not cover the structural design of culverts. It includes information pertinent to the management and design of culverts, and there is inevitably some repetition throughout the guide. This is to reduce the risk of users missing vital guidance by selective reading. However, users are urged to read comprehensively, especially if new to the subject.

Designing Streets: A Policy Statement for Scotland

Read document description

Designing Streets is the first policy statement in Scotland for street design and marks a change in the emphasis of guidance on street design towards place-making and away from a system focused upon the dominance of motor vehicles. It has been created to support the Scottish Government’s place-making agenda and is intended to sit alongside the 2001 planning policy document Designing Places, which sets out government aspirations for design and the role of the planning system in delivering these.
