Essential survey works are scheduled to take place at Preston Brook Tunnel to assess the condition of the structure and gather detailed technical information.

To carry out this work safely, the tunnel will be closed to navigation overnight between 8pm and 6am, from 13 July to the morning of 24 July. Navigation will remain open as normal during daytime hours and will be fully open over the weekend within this stoppage period.

These works follow initial investigations completed earlier this year, with the findings informing this next stage of more detailed assessment.

We have worked to minimise the impact on navigation during this period by scheduling these works overnight and appreciate your patience while this important work is carried out.

Thank you for your understanding.
