Update
We've been conducting environmental surveys and have found evidence of dormice on site.
As a result, works have been paused while we apply for a dormice licence from Natural England.
We appreciate this is frustrating but we have a duty to protect the natural environment and biodiversity.
We are expecting to resume work on site and have a revised programme of closures available by the end of March. This means the completion date of the scheme will now be the end of April, subject to weather and the wildlife licence being issued.
