This document relates to the Forth Crossing Bill introduced in the Scottish Parliament on 16 November 2009. It has been prepared by the Scottish Executive to satisfy Rule 9C.3.2(g)(iii) of the Parliament’s Standing Orders. The contents are entirely the responsibility of the Scottish Executive and have not been endorsed by the Parliament.

1.1 Background

1.1.1 The Forth Replacement Crossing (FRC) is a major infrastructure project proposed by Transport Scotland, an agency of the Scottish Government. The FRC comprises a new cable-stayed bridge across the Firth of Forth and associated new and improved roads infrastructure to both the north and south of the bridge.

1.1.2 Despite significant investment and maintenance over its lifetime, the existing Forth Road Bridge is showing signs of deterioration and is not suitable as the long-term main crossing of the Firth of Forth. In December 2007, following the completion of the Forth Replacement Crossing Study (Jacobs et al., 2007) as part of the Strategic Transport Project Review (STPR), the Scottish Government confirmed the intention to provide a new cable-stayed bridge to the west of the existing Forth Road Bridge. 

1.1.3 Jacobs Arup (as a joint venture) was commissioned in January 2008 to assist Transport Scotland to develop the FRC proposals. Following considerable environmental, engineering and economic assessment of different route corridors and options (as described in detail in Chapter 3: Alternatives Considered), key decisions were announced by the Scottish Government in December 2008 including:

  • the preferred route corridor to the north and south of the Firth of Forth;
  • the intended design of the new bridge; and
  • a managed crossing scheme, retaining the Forth Road Bridge as a public transport corridor and continuing its use by pedestrians and cyclists, and designing the new bridge to accommodate all other traffic (private cars, heavy goods vehicles etc).

1.1.4 The FRC proposals have been progressed within the preferred route corridor since the December 2008 announcement. This Environmental Statement (ES) presents the results of the Environmental Impact Assessment (EIA) of the Design Manual for Roads and Bridges (DMRB) Stage 3 engineering design as described in Chapter 4 (The Proposed Scheme).

The Forth Replacement Crossing

1.1.5 The FRC Stage 3 engineering design assessed in the EIA and reported in this ES (hereafter referred to as ‘the proposed scheme’) is shown on Figure 1.1. The proposed scheme comprises a new bridge approximately 2.7km in length, approximately 3.6km of new mainline carriageway and 1.8km of upgrades to existing mainline carriageway. The key elements are summarised below:

  • mainly online upgrade of the A90 south of Admiralty Junction to Ferrytoll Junction;
  • reconfigured Ferrytoll Junction and associated side road realignments/improvements;
  • a new bridge (hereafter referred to as ‘the Main Crossing’) to the west of the existing Forth Road Bridge;
  • new mainline carriageway from the southern abutment of the Main Crossing, running west of South Queensferry to a new junction with the A904 (‘Queensferry Junction’);
  • new mainline carriageway from Queensferry Junction running to the south of South Queensferry before rejoining the existing A90 west of Scotstoun; and
  • improvements to M9 Junction 1A to provide improved functionality facilitating all movements (east and west to/from the M9). The works also include carriageway upgrades to the M9, south of Junction 1A.

1.1.6 Further detail regarding the proposed scheme including associated improvements such as new bus links to the Forth Road Bridge and the intended traffic management strategy (Intelligent Transport System; ITS) is provided in Chapter 4 (The Proposed Scheme).

1.2 Statutory Context

The Hybrid Bill Process

1.2.1 It is intended to apply for development authorisation for the proposed scheme through a Parliamentary Bill introduced in November 2009 and processed by the Scottish Parliament.

1.2.2 The Parliamentary Bill will be in the form of a Hybrid Bill (public bill which affects private interests).

1.2.3 The Standing Orders of the Scottish Parliament (Scottish Parliament, 2008) confirm that the Bill should be accompanied by an Environmental Statement containing the information set out in Schedule 4 of the Environmental Impact Assessment (Scotland) Regulations 19991 (hereafter referred to as the EIA Regulations).

Bill Objectives

1.2.4 The primary purpose of the Bill is to seek and obtain authority for a scheme which includes the construction and operation of a new crossing over the Firth of Forth to the west of the Forth Road Bridge which will carry all general permitted road traffic thus enabling a restricted use of the Forth Road Bridge to public transport, pedestrians, cyclists and other specified users. The Bill allows works in relation to:

  • construction of a new crossing;
  • construction of new roads (including connections with existing roads);
  • improvement of existing roads; and
  • implementation and maintenance of Intelligent Transport Systems.

1.2.5 To facilitate the implementation of works, the Bill also allows for the stopping up of some roads and other rights of way where these cross or are on the route. In particular, the Bill grants compulsory purchase powers thus ensuring that Scottish Ministers will be able to acquire the land or rights in land that are required for the works to be constructed and operated.

Environmental Impact Assessment (EIA)

1.2.6 EIA of the proposed scheme has been undertaken and formed an integral part of scheme design and appraisal. The purpose of the EIA is to investigate the likely impact of the proposed scheme on the biological, physical and historical environment, as well as on members of the public and on current or planned future use of the environment.

1.2.7 EIA has informed decision making throughout the design process to address potentially significant impacts where practicable such as by refinement of route alignment, or by the incorporation of measures to prevent, reduce, remedy or offset any predicted adverse environmental impacts.

1.2.8 European Commission Directive 85/337/EEC as amended by Directive 97/11/EC regarding the assessment of the environmental effects of certain public and private projects determines the requirement for an EIA of the proposed scheme. Annex I of the EIA Directive lists large-scale or potentially high impact developments for which an EIA is always required. As a motorway in parts, the proposed scheme falls into this category. The Standing Orders of the Scottish Parliament accord with the terms of the EU Directive with respect to production of an Environmental Statement. The Standing Orders require the project to supply information as per Schedule 4 of the EIA Regulations. The proposed scheme also complies with Directive 2003/35/EC regarding public participation.

1.3 Environmental Statement (ES)

1.3.1 As noted in Section 1.2, the proposed scheme was subject to EIA, which has established detailed information about the likely main environmental effects. This ES reports on the findings of the EIA process.

1.3.2 Schedule 4 of the EIA Regulations confirms the information to be included in an ES. Accordingly, this ES provides the following:

  • a description of the proposed scheme, including details of the site and the road design, land use requirements during construction and operation, and an estimate by type and quantity of any emissions arising from the development;
  • an outline of the main alternatives and the main reasons for the choice of the preferred scheme, taking into account environmental effects;
  • a description of the aspects of the environment likely to be significantly affected by the proposed scheme;
  • a description of the likely significant effects of the proposed scheme on the environment, including direct and any indirect, secondary, cumulative, short, medium and long term, permanent and temporary, positive and negative effects, and a description of the forecasting methods used to assess the effects on the environment;
  • a description of the measures envisaged to prevent, reduce and where possible offset any significant adverse effects on the environment;
  • an indication of any difficulties encountered in compiling the required information; and
  • a non-technical summary of the above information.

1.3.3 This ES is presented as shown in Table 1.1 below:
