The A329M and the M4

The decision of Highways England to alter the slip road access at the A329M and M4 junction has caused difficulties for those travelling on the A 329 M.
I have been seeking a remedy ever since I first saw the plans, which decided to halve the road capacity on the A 329 M for through traffic in order to relieve pressure and back up on the M 4.

I was told that traffic models showed one lane was sufficient for the A 329 M , and one dedicated lane for merging M 4 traffic would help the flow off the M 4. That did not seem likely to me. It hasn’t worked out like that.

They did agree to undertake a study to see why people have been unhappy about the results of their works. As I expected this study has concluded that there is increased congestion on the A329 M following the works on the junction. They then seek to blame driver behaviour and look for solutions that will guide or direct drivers to get it to work. The truth is driver behaviour has been affected by the changes made to the road layout. Drivers do cut across from the M4 slip onto the fast lane of the A 329 M which is the single through lane because they see they have to merge with other cars on the slip.Cars have to pull out of the slow lane into the fast lane on the A 329 M because their lane disappears altogether.This can cause difficulties.

There may be modest improvements to be had from clearer signs and road markings to control where cars can switch lanes, but the real need is for more capacity which I will continue to press for.
