What we are doing

Our first tunnel boring machine (TBM), Florence, is planned to complete its journey in early February. It will then be dismantled in sections and transported off site via HGVs and some abnormal loads.

How will this affect me?
The site will operate under extended working hours:

•  24 hours per day, 7 days per week, including Saturday and Sunday. Works are planned to begin early February and will be ongoing until both TBMs are dismantled and removed, which we anticipate will take four to six months. We are working 24/7 to minimise long term impacts on the community.
• This milestone breakthrough will require extra site lighting and may create some noise. We will do everything we can to mitigate this and to keep disruption to a minimum.

The works are located deep within an embankment cutting 18 metres below ground level. To mitigate further, noise barriers remain erected at strategic locations around the site boundary to reduce the level of noise leaving the site. However, some noise may still be heard.

We have noise monitors at several locations that provide accurate readings, informing us immediately if the works generate high levels of noise. Should this happen, an investigation will be undertaken by our noise and site teams to see how the works can be further controlled.
