Please see the following table which provides the costs of upgrading the 2297 streetlights on the A90.

Bridges are inspected in accordance with the National Standard CS 450 Inspection of Highway Structures and the condition is ranked and prioritised in accordance with the requirements of The Inspection Manual for Highway Structures Volume 1 and the Transport Scotland Structures Manual.

Transport Scotland’s Ancillary Assets Scheme Development Guidance provides direction on the identification, development and assessment of potential lighting schemes to ensure that funding is spent on the most deserving sites that offer best value with a demonstrable maintenance need. The protocol requires our Operating Companies to develop a 3 year programme that details all planned maintenance works. The following table lists the current draft A90 lighting maintenance plans.

Transport Scotland officials oversee the work of our contractors. They collaborate across disciplines and contractual boundaries to ensure work is completed in the areas of most need and that it represents best value.

Officials are supported by the Performance Audit Group (PAG). PAG is employed by the Scottish Ministers to provide independent auditing of the Operating Companies’ performance to ensure that the requirements of the contract are met, that work is carried out to the required technical specification, and that financial valuations are correct.

Officials work in partnership with PAG to manage contract risks in accordance with Scottish Government policy. The most significant risks are transferred to Roads Directorate’s risk register for completeness.

Please see the following table which provides the costs of maintaining the 2297 streetlights on the A90.

There are seven emergency telephones installed on the A90 north of Dundee and two on other sections of the A90.

Transport Scotland has developed an Approach to Climate Change Adaptation and Resilience (ACCAR), which provides a strategic overview of our approach primarily on infrastructure and services directly under Transport Scotland control. A key deliverable of this work is the development of a Trunk Road Adaptation Plan, based on a climate vulnerability and risk assessment using the latest UK climate projections. The Trunk Road Adaptation Plan will be published in 2025. It includes key interventions and recommendations for further adapting the Trunk Road Network. There will be a focus on risks associated with increased surface water flooding, river flooding, river scour and landslides.

The Trunk Road Adaptation Plan will complement the work of our roads Vulnerable Locations Operational Group (VLOG), which was established in 2021 in line with the commitments set out in the National Transport Strategy Delivery Plan 2020 – 2022 with an initial focus on delivering short-term cost-effective actions, whilst developing a move to a long-term proactive approach, including a dedicated budget for climate change adaptation.

The VLOG has targeted resource on early flood level warning systems around A90 river crossings and undertaken specific bridge scour assessments and inspections to national standards to enable resources to be focused on potential future risk areas

In the past five years 51 calls have been received on the emergency telephones on the A90 north of Dundee.

The current estimated costs are £716,432.40. However, this may increase as the investigation and design for the permanent works progresses.

Construction is anticipated to be complete by the end of September 2025. However, investigations and permanent works design are still ongoing. Ecological factors at the site will also severely affect the available construction window
