Following the completion of the Forth Replacement Crossing Study
as part of the Strategic Transport Projects Review (STPR), the
Cabinet Secretary for Finance and Sustainable Growth announced to
Parliament on 19 December 2007 that the Forth Replacement Crossing
would be a new cable-stayed bridge located immediately upstream of
the Forth Road Bridge.
The decision to progress with the development of the project was
based on the findings of the Forth Replacement Crossing Study,
Reports 1 to 5 (Jacobs et al., 2007) and addressed ongoing concerns
over the continued availability of the Forth Road Bridge as an
unrestricted crossing for general road traffic. The policy
objective is to provide, in the light of uncertainties about the
future availability of the Forth Road Bridge, a continuing and
reliable primary road link between Edinburgh, the Lothians, and
Fife and beyond in order to safeguard the economy, particularly of
the east coast of Scotland.
Following the above announcement, the Jacobs Arup Joint Venture
was appointed in January 2008 to work as a development partner with
Transport Scotland to take the project forward. With the need, form
and location for a replacement crossing having been identified,
Jacobs Arup were engaged to carry out the detailed development of
all aspects of the Forth Replacement Crossing Project, including
the Main Crossing and its connecting roads infrastructure. This
included the associated environmental studies and the Environmental
Impact Assessment (EIA) and the production of an Environmental
Statement (ES), a Sustainability Appraisal and Carbon Management
Report and this Health Impact Assessment (HIA).
This HIA report presents a high-level appraisal of the possible
health effects of the Design Manual for Roads and Bridges (DMRB)
Stage 3 engineering design.
1.2 Purpose of Health Impact Assessment
The purpose of an HIA is to assess any potential health
consequences of the proposals, to use this information to make
recommendations to reduce the risk of adverse health effects and,
where possible, to improve the health outcomes resulting from the
proposal. HIA is a multi-disciplinary activity that cuts across the
traditional boundaries of health, public health, social sciences
and environmental sciences.
There is no statutory basis for HIA, although its use is
advocated in Government policy and guidance documents.
Non-statutory guidance on HIA has been produced by numerous
organisations including Health Scotland, as described in Section
3.3 of this report.
The most commonly used definition of HIA is given in the World
Health Organisation (WHO) Gothenburg Consensus Paper (1999) which
describes it as:
‘a combination of procedures, methods and tools by
which a policy, programme or project may be judged as to its
potential effects on the health of a population, and the
distribution of those effects within the population’.
This HIA draws from the findings of a number of other studies on
the FRC proposals other studies including in particular the ES and
the DMRB Stage 3 Scheme Assessment Report. It collates and assesses
facts relating to potential health impacts from these various
reports, considers them in the context of relevant baseline health
information and consolidates this information in a concise report.
