Scheme Background• Existing Issues

• The junctions are operating at the limit of their capacity…

• …and at times there is blocking back of queues between junctions

which leads to long delays and gridlock.

• … and the local road network is difficult for pedestrians and

cyclists to navigate.

• Scheme Objectives

• Provide increased capacity improvements.

• Alleviate congestion throughout key junctions.

• Improve facilities for NMUs.

• Enhance road safety at junctions.

• Minimise adverse impact on the environment.

Scheme Development

• Design

• Traffic & Ground Investigation surveys

• Modelling of junctions with traffic simulations

• Environmental and ecological surveys

• Geotechnical design

• Highway alignment

• Detailed design

• Geometry

• Drainage

• Traffic signals

• Signs, VRS etc….

Consultations during Design

Environmental Process:

• Natural Resources Wales

• CADW

• Newport City Council Officers

Design and Construction (Including temporary traffic regulation orders):

• Newport City Council Officers

• Morgan Vinci

• Sustrans

• SWTRA

• Gwent Police

• Junction 28 Forum (Including Office of National Statistics, International

Rectifier, Go Compare, Intellectual Property Office)

• Bus Operators (Cardiff Bus, New Adventure Travel,

Stagecoach)

• Bassaleg School

Bassaleg - Benefits

• Improved junction capacity with road

widening on the A467 Forge Road,

A468 Forge Road and on the

roundabout.

• Junction is now signalised allowing

smoother traffic movements by

providing balanced traffic flows

between the routes.

• Enhanced NMU facilities with

signalised pedestrian crossing on the

A467 Forge Road.

• New LED street lighting.

• New surfacing.

M4 J28 - Benefits• Improved junction capacity including

widening on the M4 eastbound off-

slip, new dedicated through road to

A48 SDR from the M4 eastbound off-

slip and Cleppa Park and elongation

of the roundabout with additional

traffic lanes and signals.

• Supplementary traffic islands to

separate flows, increasing capacity

and improving safety.

• New traffic signals for the A48 Cardiff

Road from Newport to help balance

the flows.

• Enhanced NMU facilities with new

signalised crossing points.

• New LED street lighting.

• New surfacing.

Pont Ebbw - Benefits

• Improved junction capacity with

new though-links for the A48 SDR

and road widening on A48

eastbound approach to the

junction.

• Additional lanes on the

roundabout to provide extra

capacity.

• Supplementary traffic islands

have been provided to separate

flows, increasing capacity and

improving safety.

• Full time signal control allowing

smoother traffic movements.

• New LED street lighting.

• New surfacing.

Visualisation now and afterPresent-day: blocking

Future scenario:

Congestion minimised with

increased capacity and

more traffic management

(with full signal control)

What happens next…..

• Seek Ministerial Approval.

• Commence mobilisation and start construction works

from Feb 2017.

• 16 months construction programme.

• Bassaleg & Tredegar start first.

• Pont Ebbw works commence upon completion of

Bassaleg around October 2017.
