Chamber and committees

I refer the member to the answer to the question S6W-33028 on 22 January 2025. All answers to written Parliamentary Questions are available on the Parliament’s website, the search facility for which can be found at https://www.parliament.scot/chamber-and-committees/written-questions-and-answers

Decisions on the effectiveness of operational protocols are for Police Scotland and other emergency services to consider and review as required. You may wish to contact them directly on this matter.

There is a total of 140 overbridges and overpasses (including footbridges on the A90 trunk road and within the Aberdeen Western Peripheral Road / Balmeddie to Tipperty Project boundary. All are in an acceptable condition. They are subjected to regular inspections to determine the integrity of the structures and identify any necessary repairs. Transport Scotland's Operating Company, Amey, has ongoing prioritised works at the structures below:

• A90 Glencarse overpass was struck by a vehicle in March 2023 and repairs were completed on 21 December.
• A90 Finavon Bridge sustained storm damage during Storm Babet in October 2023, work has been ongoing to facilitate repairs

The Scottish Government published the second Strategic Transport Projects Review (STPR2) in December 2022. STPR2 prioritises maintaining and safely operating existing assets over targeted infrastructure improvements. STPR2 did not recommend any major upgrades to the A90 trunk road. Instead, Recommendation 30 noted that the A90 Perth to Aberdeen (excluding the A90 Kingsway through Dundee) as an example of locations for potential future road safety improvements. Separately, Recommendation 32, identified the proposal for an integrated transport plan to be developed for the A90 Kingsway through Dundee.

In addition, the Scottish Government remains committed to delivering a new grade-separated junction on the A90 at Laurencekirk as part of the package of additional investment alongside the Aberdeen City Region Deal.

Transport Scotland has been taking forward the necessary design and assessment work, and the project is currently going through the statutory authorisation process, having recently published supplementary draft Orders for formal comment.

As with all infrastructure projects, delivery of the Laurencekirk scheme can only commence when the relevant statutory authorisation powers to do so have been secured. Following completion of the statutory authorisation process we will then be in a position to set a timetable for delivery of the scheme in line with available budgets.

All transport expenditure supports economic activity and development. This ranges from the maintenance and enhancement of the road, rail, air and ferry networks and our bridges, the impact of our sustainable travel and low carbon schemes, the support for public transport users through concessionary fares, the funding of rail services and bus grants to allow easier access to employment and support to local authorities.

Funds are allocated in line with the 4 priorities within the National Transport Strategy of which Inclusive Economic Growth is a key component and the vast majority of expenditure is around maintaining and running the existing system that is crucial for economic development. However, all transport interventions have impacts across all the 4 priorities and interact with each other and some projects are funded over multiple years and as such, there is no rigorous way of determining which expenditure in any given period has a primary focus on economic development.

Over the last 5 full financial years there has been the following number of surface repairs on the A90 trunk road:

There are 241 laybys on the A90 trunk road (including bus stops). There are currently no plans to expand these facilities at this time.

As carriageways are designed for a specific period (a ‘design life’) based on the predicted numbers of vehicles passing over that section over a specific number of years, increased traffic volumes (particularly commercial vehicles) can accelerate their deterioration. Traffic volumes on the A90 have risen by 6% over the last five years. This change in traffic has been factored into our most recent calculation of the Road Condition Index which is used to identify where detailed engineering investigations should be focused in order to determine maintenance requirements.

Evaluation is essential to the work of Transport Scotland to assess whether policies and interventions are being delivered as intended, and to help identify ways to improve them.

Discussions regarding rail safety are held between rail trade unions and relevant employers.
