A47 Blofield – North Burlingham Dualling
Project Introduction
ECI scheme which HA awarded to Edmund Nuttall Ltd in March
2004. SW are Contractors Designer and the scheme budget is
£37.5m.
Project Background
The existing single carriageway section of the A47 between the
Blofield Bypass and the Acle Bypass presents a significant
discontinuity in the standard of highway provision between Norwich
and Acle. The scheme will upgrade 3km to dual 2-lane standard and
provide grade separation of the junction closest to Acle, which
suffers from a high accident frequency due to large numbers of HGVs
turning. Other junctions will be closed, except for a partial
movement junction for westbound traffic at the western end.
Notoriously congested where the single carriageway commences, with
a high proportion of HGVs.
Project Scope
The objective of the scheme is to improve safety for all users,
to improve access to local facilities and the wider transport
network for all travellers, and to reduce congestion on the A47 by
removing the bottleneck of the single carriageway section whilst
delivering an environmentally acceptable scheme that protects and
enhances the built and natural environment.
Scott Wilson’s services have included highway design, structural
design, geotechnical advice, environmental assessment and design,
traffic and economics analysis, drainage design, landscaping,
street lighting and signing design, as well as the design
management and assisting the Highways Agency in the Statutory
process by preparing the draft Orders. Scott Wilson will be
providing expert witnesses and support to the Highways Agency
during the Public Inquiry. During the schemes construction phase,
Scott Wilson will be providing construction supervision.
Value Adding Project Achievements
Design seeks to minimise import of material and the new
carriageway is set in cutting, to maximise the cut-fill balance for
the scheme as a whole. New tracks to maintain means of access to
land and property will be constructed using recycled pavement
materials.
