A 4 month project by the Canal & River Trust to carry out essential maintenance within Netherton Tunnel. 
Due to the nature of its design and as a result of the local ground conditions, cracks have appeared in the Victorian brickwork with many 'bunching up' and breaking off. This has caused serious concern for our engineers which have now started the repair works that will safeguard the tunnel's future.
The project will cost £1.5million and involves carrying out repairs to a 50 metre centre section of tunnel almost a mile into the tunnel. Engineers are drilling holes within the tunnel wall, filling these holes with steel tubes which are then filled with concrete. Once set this section of tunnel will also be reinforced with a new arch to create a stable centre section.
