Remedial works were carried out at this location earlier this year but unfortunately they were not successful. We reported just a few weeks ago that the works had failed to eliminate the problem and we were assured then that a further investigation would be carried out. We are still awaiting the outcome of that investigatory work (please see post dated 13 March 2016 for background information).
We will report on progress with this matter as soon as we receive further information from highways engineers.
