on: The need for the project and whether a tunnel was the most appropriate solution The preferred tunnel route (including the detailed alignment of the tunnel) Preferred sites and permanent works (taking into account the feedback received from the first phase of consultation such as the move from greenfield to brownfield sites) Detailed proposals for the preferred sites (again taking into account feedback from the phase one consultation) The effects the project would have (as outlined in the preliminary environmental information report) A total of 1,374 feedback forms (online and hard copy), 4,636 pieces of correspondence and nine petitions were received. Following this consultation, and taking into consideration all the feedback received, the proposed route was finalised as the Abbey Mills route and the preferred construction and drive sites were identified. Several sites were also identified as needing further, targeted consultation which resulted in further refinement and improvement of designs at those sites.
