M-way worries

AS THE consultation on the new M4 closes, people calling for a new motorway through the Gwent Levels say that it’s needed on economic grounds, but fail to justify this. No economic model has been published that can justify spending £1 billion on a new motorway. Building a new motorway to reduce congestion will only generate more congestion. This occurred on the A34 Newbury Bypass, which the predicted traffic levels for 2010 were reached in 2003.

The M4 around Newport in mainly used by local traffic, not long distance through traffic. Reducing congestion can only be attained by a shift away from cars to public transport, cycling and walking. For example, the proposed South Wales Metro could take a lot of this traffic, as could properly integrated public transport interchanges, but not like the current example of the redeveloped Newport Bus Station. New railway stations at Llanwern, Magor and to the west of Newport would help too.

The estimated cost of over £1 billion for the motorway could be better spent on providing the above measures. This would generate more jobs, produce less pollution and carbon emissions and be more sustainable.

The idea that roads create congestion is a fallacy and ignores the major issue in this case.

The problem with the existing M4 is not the volume of traffic it is being asked to hold, but that the road is inherently unsuitable for use as a motorway with sharp corners and rapid gradient changes, combined with too-frequent entry and exit points.

The structure of the M4 around newport is better suited to a local ring-road and it should be combined with the SDR and used as such. However, in order to do so it will be necessary to construct a new section of the M4 to link into this ringroad and carry normal motorway traffic around Newport.

This would form part of a joined up transport strategy for south wales, including use of the proposed metro system and electrification of the railways and would reduce overall environmental impact by limitting the amount of time vehicles spend in traffic jams, emitting apparently harmful exhaust fumes without moving anywhere.

Mr Yates has obviously not queued from the SSC with all the other local (!!!) traffic. What a plo***** !

you've got a good point, why ruin it with "apparently harmful exhaust fumes"?

There would be a number of consideration and economic grounds would be one as well as reducing congestion and pollution and reducing the accident rate

Even without a report it is pretty clear that the current Newport section of the M4 is not suitable as a motorway.

Possibly the best option might be to use the current section of the m$ as a Newport bypass with a 50 MPH speed limit and build a new section that meets current motorway standard to replace it

Even with this J28 needs upgrading it is operating at capacity. The only real answer is a flyover or underpass particulary as any replacement would require a reduction of junction on the M4 so J28 would get busier
