To ask the Scottish Government what factors are considered prior to closing a trunk road for upgrading; who is consulted; what assessment it makes of the impact of closures, and what plans it has to review the process.
The Scottish Government fully recognises the importance of the trunk road network to the economy of Scotland and also the communities which it serves. That is why this Government has invested almost £1.5 billion in the maintenance of the network since 2007.
The Government and the national transport agency (Transport Scotland) also appreciate that these vital maintenance works, which are a legal duty on Scottish Ministers under the Roads (Scotland) Act 1984, can be disruptive to businesses and communities. That is why maintenance contractors (Operating Companies) develop a programme of works which seeks to consider and balance these maintenance duties with disruption to journeys.
Factors Considered
Where possible, and where safe to do so, programmes are developed to avoid road closures but also to avoid peak tourist seasons and busier weekdays/times. The Operating Companies also work with local authorities and other stakeholders to review what events may be impacted by any works.
Other factors which influence the traffic management options for works include: -
-
road width (for public and road worker safety),
-
impacts on ferry/rail/bus services and HGV deliveries
-
weather (repairs are better quality and more value for money in good weather)
-
impacts on journey times (from traffic models)
-
available diversion routes & length of diversion
-
traffic flows (volumes, type, purpose)
Unfortunately, even after considering all of this, sometimes closing a trunk road for works is the safest option. This is generally in areas of narrow road widths, where the minimum standard of traffic management required to keep operatives and the public safe does not leave space for traffic to pass.
Scheme Consultation and Assessment
Appropriate consultation is key to the successful delivery of works. The expected disruption from works determines the level of consultation undertaken. For example, gully clearing and grass cutting would likely have no consultation, whereas extensive and deep road repairs would have detailed pre-work engagements. For the larger works, the ‘consultation’ phase of this engagement would generally include contact with emergency services, councils, public transport operators, community groups, the haulage industry, elected members, chambers of commerce and letter drops to affected properties. The feedback from these parties helps to influence the timing and traffic management decisions.
This stage is followed by notification which can include press releases, updates in websites/social media, radio broadcasts, signs on road and emails/letters to stakeholders advising of the scheme details.
For the more disruptive works, the Operating Companies run traffic models to help determine the impacts on journeys. This information is used in the decision making for the choice of traffic management, the timing of the works and also the requirement for diversion routes.
Reviews of this process
Transport Scotland and the operating companies regularly review this scheme development and consultation process, sharing improvements across the various operating company contracts. Recently, this has seen changes that have meant earlier consultation with some parties and widening consultation to include community groups on the longer diversion routes. These changes are often driven by previous consultation responses. Further reviews of the process and associated improvements will be undertaken throughout the life of the maintenance contracts.
I hope that this demonstrates that we are listening to the feedback from road users and businesses. Everyone appreciates that necessary maintenance works can be disruptive but it is important that these works are developed and delivered in a safe manner that balances the needs of the network and the communities and businesses it serves.
