Autolink Concessionaires (M6) said it had agreed an £18m settlement with consortium of contractors over the design and construction of a section of the A74(M) in Scotland.
This follows action brought by the company against the contractors in the Court of Sessions in Scotland.
A statement said: “The company considers the settlement with the construction joint venture is adequate to cover future remedial costs.”
The settlement is payable within 10 working days.
