For many years Noise has been an issue on the A3M, and my predecessors have lobbied for improvement.
There are strong views that as people moved into an area near the A3 and A3M they knew it would be a noisy environment. There is a lot to this, but over the life of a road surface as it deteriorates the noise levels increase, as they do with increased traffic, so the noise levels are increasing. Some people residents in Horndean also remember life before the A3 turned into a dual carriageway.
Either way we should seek to improve our environment wherever we can and reducing noise levels on the A3 is one such area. A set of noise levels I measured recently showed readings of 69Db to 75Db on the pavements and side roads near the A3. At 80Db in a work place the employer needs to provide hearing protection.
In the last year or so we have seen patches of resurfacing work carried out, and for those who drive on the road, the noise difference in the car is striking when you drive on and off of one of these new strips. Since my requests for information to the Highways Agency public enquiries line were being met with little response I used the Freedom Of Information Request tool again. I must say, I am warming to the FOI process.
An enquiry asking what noise mitigation measures or maintenance works are planned identified that the Highways Agency are NOT currently planning to reduce noise levels but are carrying out targeted resurfacing for necessary maintenance. A map of this is below:
It looks like the resurfacing is to run over the hill beyond Clanfield, and the stated duration is October 2013 for 3 months. this general resurfacing will make a noticeable improvement.
A second question asking of they were planning on any acoustic fencing (which would, I believe, significantly improve the quality of live to properties along London Road, and 100 to 200m into Downs Ward) resulted in a statement that there were no plans in place, but noise maps prepared by DEFRA have been used to prepare Noise Action Plans. This document apparently sets out how noise is to be managed, and I am trying to get a copy of it…
In the meantime the DEFRA map identifying the parts of the local road network where noise levels are high enough to be an issue is below:
