The proposed scheme
Description of the Project
The proposed works will entail replacing the existing bridge with a new structure. The existing bridge follows a single track alignment as shown on the photograph opposite. The new bridge will be upgraded to a standard single carriageway width and allow for the eventual upgrading of the short section of single track road lying immediately to the west. There will be no predicted increase in traffic flows as a result of the proposed scheme.
The proposed work includes installing a concrete box structure with an otter ledge on one side. The base of the box structure will be lower than strictly necessary to allow a more natural bed of sediment and gravel to be provided. In addition, boulders will be secured in the stream bed to provide a low-flow channel that migratory fish can pass through.
In order to accommodate the new structure and facilitate safe working, the historic masonry arch bridge lying directly upstream of the trunk road bridge will require to be demolished. The proposed works will need formation of a temporary diversion route to the north of the existing A887 Allt Lagain Bhain Bridge and realignment of a short length of the Allt Lagain Bhain watercourse back to its original line.
The proposed working area during construction is anticipated to be slightly less than 1 hectare as shown in Figure 3 in the previous chapter.
Consultation
Consultation is a key and fundamental part of the Environmental Impact Assessment process. Chapter 4 of the Environmental Statement describes the consultation undertaken throughout the various stages of the Environmental Impact Assessment process and provides a summary of the key issues raised by consultees. It also includes relevant responses from consultations that were undertaken as part of the Scoping Report.
The following statutory and non-statutory consultees have been consulted to inform the assessment:
- The Scottish Environment Protection Agency (SEPA);
- Scottish Natural Heritage (SNH);
- The Highland Council Historic Environment Team;
- The Ness District Salmon Fishery Board; and
- The Ness and Beauly Fisheries Trust.
