Thank you for your feedback on Access to Argyll and Bute (A83) corridor route options.

Public consultation on the 11 corridor route options took place between 23 September and 30 October 2020. This initial consultation is now closed and we would sincerely like to thank all those who participated in the consultation and shared their views. During the five week consultation we received in excess of 650 responses. These responses highlight a range of issues and provide valuable information for the project team to consider as design and assessment work progresses.

We plan to publish a report on the consultation findings once everything has been considered, however, in the meantime, the following provides a brief summary of the emerging issues and themes that respondents have fed back to us.

Emerging Issues and Themes

Feedback from respondents noted the following issues and themes:

  • A long-term solution is needed – the chosen option should take account of future needs and changes.
  • The scheme must be developed quickly.
  • Reliability and resilience - impact of disruption and delay caused by closures on residents, businesses and through traffic.
  • Road safety issues due to landslides, flooding and congestion.
  • Poor connectivity for communities.
  • Support the local economy.
  • Provide an effective alternative to ferry crossings.
  • Minimise environmental impact of the proposed scheme and make use of existing routes.
  • Cost and value for money of proposed scheme should be taken into account.
  • The scheme should consider or include safe and accessible routes for walking, cycling and horse riding – including tourism and other recreational use.
  • The scheme should take account of climate change, in terms of modal shift as well as mitigation and adaptation measures.
  • The scheme should allow for a phased development - enabling current issues to be addressed quickly with minimal disruption to road users, while allowing for further improvements in the future.
  • The existing A83 should be maintained and kept open during construction – or a replacement route provided to minimise disruption while works are taking place.
  • Prioritise addressing the issues at the Rest and be Thankful.
  • Views of local communities should be considered.

Whilst not explicitly asked in the consultation, many respondents took the opportunity to state their preference on which corridor or corridors should be taken forward for further consideration. We are currently reviewing these comments on corridor preference and the findings will be included in the subsequent report.

Method of Consultation

The consultation also sought feedback on the virtual sharing of information on this project, and encouraged consultees to suggest any alternatives:

Brief summary of the responses on virtual sharing

  • Respondents stated that the arrangements for sharing information and contacting the project team were good or adequate, and the consultation arrangements were suitable / appropriate in the context of the COVID-19 pandemic. Others suggested phone or email continue to be used as methods of communication for the project (as proposed).
  • Respondents also commented that the visual materials (i.e. the website and maps or graphics) were useful.
  • Comments received noted that the online consultation may not be accessible to anyone who was not  computer literate or who lacked internet access.
  • Indications were that more engagement was needed – particularly with local communities who would be most affected. This included comments that there had been a lack of engagement so far, or that there was a lack of local awareness of the consultation. It was suggested that local communities should be included and prioritised in future engagement.

Respondents' feedback on alternative methods for future engagement on the scheme and suggestions for methods to be used included:

  • online engagement tools (e.g. Skype, Zoom etc)
  • social media (Facebook and Twitter)
  • a project website with regular updates
  • face to face engagement events
  • updates on the scheme and future engagement in local press.

The feedback we have received will help inform our assessments of the corridor options as we work towards recommending the preferred corridor for the project by Spring 2021.

Public engagement is extremely important to us - it's a vital part of our work as we develop our plans. We'll be keeping you informed of progress as part of our commitment to ongoing and considered engagement. Project updates, news and details will be posted in a new dedicated Story Map section on our website which will be launched soon, and there will be further opportunities to share your feedback as the design work is further progressed.

We look forward to your continuing interest and engagement in this project.


The section of the A83 between Ardgartan and the Rest and Be Thankful car park has a history of hillside instability, in particular on the slopes above the Rest and Be Thankful.

A83 trunk road passing through mountain scenery

The Rest and Be Thankful is the highest point on the A83, separating Glen Kinglas from Glen Croe. It is also one of the places in Scotland with the highest risk of landslides and debris flow hazards. These have increased in recent years due to the frequency of heavy, intense and prolonged periods of rainfall.

Following a number of landslides in 2004, Transport Scotland carried out the Scottish Road Network Landslides Study. As part of this study a hazard assessment and ranking exercise was carried out for debris flow. From this assessment the A83 Ardgartan to Rest and Be Thankful is one of the most highly ranked debris flow hazard sites in Scotland.

As part of the £82 million invested in the maintenance of the A83 since 2007, over £13.6 million has been invested in landslide mitigation works at the Rest and Be Thankful. This was to help keep Argyll open for business by reducing the impact of landslides on the A83.

We are aware of the A83's importance as the primary route to Argyll. In 2012, the A83 Route Study was carried out to identify and assess potential options to minimise the effects of road closures.

Our objectives then were to:

  • reduce the impact on journey times by reducing the frequency and duration of road closures caused by landslides
  • reduce the economic impact to the A83 study area by reducing the frequency and duration of road closures.

The resulting landslide measures have seen the opening of the alternative military road, installation of nets, catchpits and improvements to drainage at this location. These interventions have already proven to be successful, helping to keep the A83 open for an estimated 48 days when it would otherwise have been closed.

We continue to explore ways to reduce the risk of impacts caused from landslides in the area.

Construction of the next roadside catchpit at the Rest and Be Thankful, a project valued at £1.2 million, is currently scheduled to be built between this September and March 2021. Once complete, the Phase 1 catchpit will provide an additional 4,600 tonnes of volume to collect debris flow from landslides, to add to the 15,000 tonnes provided in the existing four catchpits.

We have also progressed the programme to proactively plant trees on the hillside to help reduce the risk of landslides in the area. Land purchase at the Rest and Be Thankful has completed and we are working closely with Forestry & Land Scotland to reintroduce the required local provenance native vegetation on the hillside.


Two phase strategy

The mitigation works to the existing route form a substantial investment to help reduce the risk of road closures. However, most recently, it appears that severe weather (rainfall) and the associated landslip events are becoming more frequent. It is unknown if this will continue or even worsen in future. Therefore, further action is being taken to provide safe, resilient and sustainable access to Argyll and Bute.

Transport Scotland is now taking forward the project development work needed to deliver an alternative route to the existing A83, in parallel with the second Strategic Transport Projects Review which is underway.

Inevitably, new roads come with associated impacts for those living and working alongside them. It is important that we follow the correct statutory process to ensure a fair and transparent assessment of options and impacts on local residents and communities.

In particular, part of the area’s intrinsic value is the outstanding landscape we will be working in. Developing a resilient and sustainable route that works in harmony with its surroundings and continues to support the associated tourism economy which is so important to the area is essential.

Transport Scotland is committed to placing public engagement and meaningful dialogue with directly affected communities and other stakeholders at the heart of the development and delivery of our plans for improving the route.

We want to ensure that communities have the opportunity to comment on the proposals for the proposed project at every stage in the process.

We recognise that the timescales for an alternative to the current route are frustrating for the local community. However, given our considerable experience in developing other rural routes such as the A9 and the A96, it would be misleading to pretend otherwise. In recognition of the pressures that the current situation brings to local communities and businesses, we are committed to progressing substantial shorter term investment in the existing A83 as part of a two-phased approach.

This work underlines the Scottish Government’s commitment to continued work with key stakeholders to ensure that Argyll & Bute remains open for business.

This web page explains the process that we will follow and how stakeholders and the public will have the opportunity to be involved. The initial eleven route corridors which are under consideration are available to view.

The challenges

Transport Scotland will work with key agencies, local authorities and local communities to address the challenges, which include:

  • working in challenging landscapes
  • construction of new major structures
  • managing the impact on the many environmental designations in the area and safeguarding the outstanding landscape
  • improving access to tourist and recreational sites
  • minimising impact of construction on road users and local communities.

Stages of necessary development work

As work on the programme progresses, Transport Scotland will ensure that arrangements for participation by stakeholders and members of the public are inclusive, open and transparent. We will encourage a wide range of participants to get involved and provide their comments and feedback.

All proposals are developed following the Design Manual for Roads and Bridges (DMRB) as used on all major infrastructure projects.

Planning permissions will be obtained through the Roads (Scotland) Act 1984.

Stage 1 (Strategic Assessment)

  • Strategic planning and appraisal of transport interventions for Argyll is being progressed through the second Strategic Transport Projects Review (STPR2) which follows the publication of the National Transport Strategy in February 2020
  • STPR2 is underway and for this project we will work in parallel with the STPR2 process, which will be the strategic business case for transport investment in Scotland for the next twenty years
  • Eleven route corridors have been generated through the STPR2 process.  This process included stakeholder engagement about problems and opportunities, both regionally and nationally, and included options workshops 
  • Read more information on STPR2, including key publications such as the Argyll & Bute STPR2 Initial Appraisal: Case for Change
  • The Case for Change for Argyll & Bute evidenced the disruption impacts and resilience concerns relating to the trunk road network in Argyll, particularly the A83 at the Rest and Be Thankful
  • Transport Scotland has appointed a project team from Jacobs Aecom to assist in the further development and appraisal of options for the A83 within Argyll. The team will carry out a strategic environmental assessment supported by associated preliminary engineering work
  • The outcome will be identification of a preferred route corridor in March 2021. Opportunities for stakeholder and public comment and feedback will be provided throughout the design and development process as new information becomes available and/or local knowledge is required
  • Sifting assessment work will now start on these eleven corridors and we are inviting local feedback on any key issues or constraints that would inform that process.
  • This stage will also include further evidence gathering to assist the design development process, such as bespoke topographical (landscape physical features) and environmental surveys, traffic and business surveys.

Stage 2 (Route Options Assessment)

  • Development and assessment of route options within the preferred corridor
  • This includes an engineering and environmental assessment of the potential impacts of each option which will inform the route choice
  • During this stage, the options will be made available for consultation
  • Following this assessment and consultation, the preferred option is then selected and taken forward to the detailed stage.

Stage 3 (Design and Assessment of Preferred Option)

  • Detailed assessment and definition of the preferred option
  • An Environmental Impact Assessment Report is prepared, and the land required for the project is also identified.

Statutory Process (Publication of Environmental Impact Assessment Report (EIAR) and Orders)

  • The draft Compulsory Purchase Order (CPO), which defines the extent of the proposed land required to deliver the project, the draft Roads Orders, which define the line of the proposed infrastructure, and the EIAR are published
  • Any statutory objections, which are lodged during the defined period but remain unresolved, are then considered at a Public Local Inquiry (PLI)
  • If the objections are upheld following the PLI, the project may have to be amended and taken through the statutory process again
  • If the objections are resolved or dismissed, then the draft Orders are finalised and made
  • Following the publication of the Made Orders, there is a legal challenge period. After this point the legal permissions have been obtained and the preferred option can proceed with the necessary acquisition of land.

Procurement (Tender process to appoint a works contractor)

  • Prior Information Notices (PIN) are issued and Contract Notices follow - inviting suppliers to express an interest in the procurement
  • Pre-Qualification process is used to shortlist suppliers that will be invited to tender
  • An Invitation to Tender (ITT) is issued to the shortlist of suppliers. The tenders are evaluated by Transport Scotland, a supplier is selected, and the contract is awarded. The preferred option can then move to the construction phase.

Public engagement and consultation

Transport Scotland takes public engagement seriously - it's a vital part of our work as we develop our plans. We will consult with a wide range of parties including agencies, local communities, road users and the general public. Our recently published story map virtual exhibition sets out how we have, and may engage, in a virtual sense through the early stages of this project, subject to COVID-19 restrictions.

Please use the table below to find out how we will consult the public during the course of the project.
