Assessment of cumulative effects

The proposed works are not anticipated to result in significant environmental effects. Due to the nature of the proposed works (i.e., primarily maintenance of existing infrastructure), no cumulative effects are anticipated with any other developments in the vicinity.

A search of the LLTNP Planning Portal identified no approved planning applications within 300m of the schemes, in the last 6 months.

A search of the Scottish Roads Works Commissioner website has identified that no other roadworks are noted as being planned in this area of the A83 trunk road at the same time as these schemes.

However, BEAR Scotland has programmed works at A83 Butterbridge and A83 Easn Dubh, located approximately 2.1km and 1.5km north of the A83 RaBT Barrier Repairs (Revision 2), respectively. These schemes are currently scheduled to be undertaken in August and early September 2026. If the current TM arrangements remain unchanged, the schemes would conflict with the TM required for the A83 RaBT Barrier Repairs (Revision 2) should they be undertaken concurrently. To avoid cumulative effects, only one set of TM will be permitted on the A83 at any one time where schemes are within 5km of each other and operate during the same working hours.

These works take place along a section of the A83 that has been subject to a high degree of modification in recent years. This scheme forms part of several phases of temporary remediation works being carried out to protect the A83 until proposed medium-term and long-term solutions can be constructed. As such, some cumulative noise and visual disturbance effects are anticipated due to the increased frequency of personnel and plant presence as well as cumulative landscape modification. However, it is expected that the medium-term and long-term solutions will involve significant areas of works that are likely to encompass most of the temporary remediation works that have been constructed at RaBT and will result in a wider area of impact. The medium-term and long-term solutions are being designed with input from LLTNP and will include assessment and mitigation of visual landscape impacts at appropriate scales for those schemes.

BEAR Scotland programme all of its proposed works in line with appropriate guidance and contractual requirements. All schemes are programmed to take into account existing and future planned works, with a view of limiting any cumulative effects relating to TM. This approach allows BEAR Scotland to effectively manage the potential cumulative effects as a result of TM, resulting in minimal disruption to users of the Scottish trunk road network.

Overall, it is unlikely that the proposed works will have a significant cumulative effect with any other future works in the area.
