Bouygues Travaux Publics has financed, designed and constructed a second tunnel under the River Tyne and refurbished the original tunnel. Operated by the Group, the twin-tunnel crossing improves traffic flow on the A19 highway linking the north and south of the Newcastle-upon-Tyne region. During the entire period of the project, targeted actions were put in place to ensure the protection of the environment. To give one example, the dredging of the river was organised outside the migration period of salmon.
