  1. Severn Bridge Operations

    I am writing to request information under the Freedom of Information Act 2000 regarding operational decisions affecting the Severn Bridge. Specifically, I seek clarification and details on the following:

    1. The reasoning and evidence of incidents behind the decision to no longer filter off high-sided vehicles during adverse weather conditions. As I believe the reasons quoted on your website suggest negligence and cause more harm than save and affect thousands of journeys.

    2. The policy or operational guidelines that inform decisions to close or restrict access to the Severn Bridge, including changes implemented in recent years.

    3. Any risk assessments, studies, or reviews conducted to support this change in practice regarding high- sided vehicles and overall bridge closures.

    4. Communication or consultation records with stakeholders (including transport organisations and safety bodies) about this change in protocol.

  3. Delays to A63 Castle Street upgrade scheme

    Requesting information on ground data around delays to A63 works including dates that show when NH became aware of the issues. Both data for pre start phase and current data requested to compare finding.

    Clarification 17/01/2025:

    In relation to the scheme National Highways is currently undertaking on the A63 castle street underpass, the FOI request is in relation to the scheme being delayed by 1 year.

    As I understand by the progress update provided by NH "we have encountered some extremely challenging ground conditions the could not have been anticipated before the scheme began" the information I'm requesting are ground data / radar information, any ground condition surveys NH carried out whilst in planning stages of choosing the location for the underpass and the details that NH now claim to be aware of at its current stage.

    Also programming schedules and plans for the scheme when it started and the revised version due to the delays.
