The tunnel suffered extensive damage, including to electrical systems, lighting, communications, and the road surface. As a result, the tunnel will remain closed to all traffic for the foreseeable future while specialist contractors work to restore communications and power and check if the tunnel is safe and stable enough to reopen.
While the tunnel is closed, we’ll also use the opportunity to carry out any maintenance and improvement works that may be necessary.
We understand the inconvenience this closure may cause. The safety of road users is our top priority, and we are working to reopen the tunnel as quickly and safely as possible.
Please do not attempt to visit the site. It remains unsafe and is restricted to authorised personnel only.
A full diversion route is in place via Canterbury Road East, London Road, Grange Road, St Augustine’s Road, Paragon, Royal Approach and Military Road.
