Timeline and documents
We are currently carrying out options assessment work and intend to carry out a public consultation on a shortlist of options. The results of this, together with the outcome of our wider options assessment work, are scheduled to be reported to our cabinet in 2026. Depending on the outcome of this work, we may also recommend a preferred option for a Norwich Western Link at that stage.
A timetable that sets out estimated future milestones will be produced at the point at which we have a preferred option.
For more information on the latest update on the project, please visit About the Norwich Western Link.
