Soboh M. Jessop J.Barnard 0 SUBMISSION June 2018 June 2018 June 2018 Lake Lothing Third Crossing Design Report Document Reference: 7.5 --------------------------------------------------------------------------------------------------------------------------- Foreword This Design Report relates to an application (“the Application”) submitted by Suffolk County Council (“the Applicant”) to the Secretary of State (through the Planning Inspectorate) for a Development Consent Order (“DCO”) under the Planning Act 2008. If made by the Secretary of State, the DCO would grant development consent for the Applicant to construct, operate and maintain a new bascule bridge highway crossing, which would link the areas north and south of Lake Lothing in Lowestoft, and which is referred to in the Application as the Lake Lothing Third Crossing (or “the Scheme”). This Design Report has been prepared in accordance with the requirements of section 37(3)(d) of the Planning Act 2008 and regulation 5(2)(q) of the Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009 (“the APFP Regulations”), and in compliance with relevant guidance. Lake Lothing Third Crossing Design Report Document Reference: 7.5 --------------------------------------------------------------------------------------------------------------------------- Executive Summary This Design Report (“DR”) has been prepared to accompany an application for a Development Consent Order (“DCO”) on the Lake Lothing Third Crossing (the “Scheme”) in Lowestoft. The Scheme is located central to the current two crossings over Lake Lothing in Lowestoft; Mutford Bridge in the west, and the A47 Bascule Bridge in the east at the inner harbour entrance. The existing crossings do not meet the current and future traffic demands, with congestion and delays to journeys being common place in Lowestoft. The height of the current bascule bridge requires it to raise for any vessel, which also adds to delays. The distance between these two crossings can make journeys unnecessarily long and inconvenient for pedestrians and cyclists. The DR provides a summary of the approach to good design, and demonstrates the response to the Vision, constraints, and considerations of the site in the reference design. The DR explains have the design evolved through various iterations and consideration of alternatives. It aims to describe in clear terms, how the design team arrived at the proposals submitted in DCO, the rationale and level of detail included. The DR concludes by introducing the Design Guidance Manual, which outlines the approach to be taken for components of the Scheme through detailed design. It also summarises the compliance with the overall vision for the Scheme and the design narrative.
