Document updated and re-structured. This document replaces the policies and guidance contained within the two previous documents: ‘Manx Roads: A Guide to the Design of Residential Roads, footpaths, parking and services’ and ‘Manx Roads 2: Residential Roads Construction Guide’, which were published in April 1993 and January 1997 respectively and are now withdrawn. The Manual for Manx Roads (MfMR) is available online via the Government website. MfMR will be reviewed at regular intervals to ensure that it accurately reflects current guidance and policies as well as changes in working practices. Users are advised to consult the Government website to ensure that they are using the most up to date version of the document.

Page 2 GN-00-019 Rev 2.00 Foreword Everyone relies on the highway network to provide good access to services. People use the network to get to work, shops, education and healthcare facilities, whilst businesses rely on the network to enable raw materials and finished goods to be transported efficiently to their markets. My Department is the custodian of the Isle of Man highway network, responsible for ensuring the safety and well-being of all road users. We are committed to ensuring that our national infrastructure assets are constructed to the best standards that we can reasonably afford. Our aim is to develop, regulate and maintain a safe, modern highway network that is fit for purpose today but anticipates the opportunities the future brings. A network that is designed for people, reflects the needs of different road users and accommodates all modes of transport. We will promote quality, innovation and sustainability but be considerate of economic and environmental factors. We will encourage collaborative working with all stakeholders to rinted create healthy, viable and more inclusive environments for the people of our Island. This guide is a key element in our drive to allow us and our partners to deliver this strategy. led when p led Hon Tim Baker MHK Minister for Infrastructure Uncontrol Page 3 GN-00-019 Rev 2.00 Purpose The Manual for Manx Roads (MfMR) is published by the Isle of Man Government’s Department of Infrastructure. Our aims are: to ensure the highway network enhances accessibility to goods and services and encourage a diversity of transport modes to ensure the highway network provides for safe interactions between transport modes to maintain a safe, inclusive and serviceable highway network The MfMR design guidance should be used by all practitioners whose decisions will result in changes to the Island’s roads, and as such is a reference source for: Department of Infrastructure officers Government Departments and Boards developers architects design engineers local authorities the public All new development requires some new highway infrastructure, ranging from a simple access onto an existing road or footway, to new street layouts serving many houses or mixed use commercial and industrial developments. The MfMR sets out design principles, processes and appropriate geometric and technical requirements for street design and public space for those involved in the planning, design, approval, construction and maintenance of highways and developments. Its content reflects current best practice, standards and guidance and reference is made Uncontrolled when printed Uncontrolled throughout to the Manual for Streets (MfS) and Manual for Streets 2 (MfS2). It recognises the importance of streets in promoting health and well-being, safety and security and in meeting the Government’s wider aspirations outlined in the Programme for Government, the Road Safety Strategy and the Active Travel Strategy to provide new, safe places for people to live, work and play, promoting healthy lifestyles and environmental sustainability. It incorporates current design thinking, promoting design principles, and clear, concise and collaborative ways of working from concept to completion. It provides technical guidance for more flexible designs to provide a well-balanced, safe, accessible and easily maintainable highway network with distinctive high quality infrastructure. This guide is applicable to new residential, mixed use developments, as well as commercial and employment-led developments, and for the assessment and review of existing streets with a speed limit of 30 mph or below. Page 4 GN-00-019 Rev 2.00 Generally, vehicular access points on roads with a speed limit of 40 mph or higher, or where 85th percentile speeds are more than 37.5 mph shall be designed in accordance with the Design Manual for Roads and Bridges (DMRB). Where there is an absence of specific advice within this guide, the design and construction of works on existing or proposed infrastructure, shall comply with the DMRB. This guide recognises that the design of streets and the development these serve are multipart. It requires an understanding, consideration and integration of the setting and the bringing together of the many functions provided, including place, movement, access, drainage and parking. Compliance with this guidance will result in a highway network which is safe and accessible for all road users, is suitable for all modes of travel, and which is buildable and affordable in relation to its future maintenance needs. rinted led when p led Uncontrol Page 5 GN-00-019 Rev 2.00 Introduction This document describes current best practice and sets the quality standard that the Department will accept. We expect designers to follow the design advice in this guide and show with supporting information how their scheme complies with it. We will consider flexibility in some areas of street design where there are no absolute requirements, such as relating to highway safety. Where designers propose a design or feature that does not accord with this guidance, advice and other parameters, it will be necessary for designers to justify their departure from our quality standard with supporting evidence that a better or more appropriate solution exists. The Department is charged with fulfilling the various statutory duties set out in the Highways Act 1986 and other relevant legislation. Roads intended to be put forward for adoption under section 4 of that Act must comply with our design and construction criteria. The Design Process from Policy to Implementation MfMR sets out the processes to be followed to ensure consistency in delivering well- designed streets, spaces and developments. We encourage early engagement to save resources as schemes are more likely to require fewer changes as they go through the planning and technical approval stages. The life of a scheme, from conception through design and implementation to maintenance can be broken down into a number of stages. The relevance and importance of each stage will vary from scheme to scheme depending on the size of the proposed development but the key stages can be summarised as: Design Principles and Movement Framework Uncontrolled when printed Uncontrolled Preliminary Design Quality Audit Planning Approval Detailed Design and Implementation Monitoring Guidance for each of these six key stages is dealt with in more detail in the relevant part of MfMR as outlined below. Page 6 GN-00-019 Rev 2.00 Part One – Design Principles and Movement Framework (Creating a Better Place to Live and Travel): provides guidance on recognising and understanding the need for good highway design, and identifies government policy and objectives that a designer should encompass within the highway design. Part Two – Preliminary Design: indicates the acceptable design criteria for the highway making up the public space which facilitates all public activity. This includes streets, paths, the circulation and storage of motorised and non-motorised traffic and other related components. Part Three – Quality Audit: provides guidance on carrying out quality audits required to assess compliance with Department’s objectives. Part Four – Planning Approval: shows how the Department assesses planning applications. It provides advice to developers, their architects and designers on the highway and traffic information which the Department requires to assess a planning application. Part Five – Detailed Design and Implementation: provides guidance on road construction, the road adoption process and undertaking work within the highway. It rinted includes information on the technical design of new roads, the specification of materials and standard
