Structural assessments have identified concerns with the bridge that require immediate action to ensure safety and keep the bridge open.

To address this issue, temporary traffic management is necessary while we work towards medium- and long-term solutions.

  • Weight Restriction – The bridge will have a 3.0 tonne weight limit.
  • Lane Reduction – Traffic will be reduced to a single lane running across the bridge. Temporary traffic lights will manage traffic.
  • Pedestrian access: Pedestrians will still be able to use the bridge.

These measures are being implemented to reduce stress on the bridge structure and maintain safe passage for vehicles while we collaborate with specialist consultants to formulate both medium-term and long-term solutions to resolve the identified structural issues.

We will continue to monitor the condition of the bridge regularly, as well as the effectiveness of the traffic management.

We do not currently have a completion date for the work, and the temporary traffic lights and single-lane arrangement are expected to remain in place for an extended period until a suitable solution is implemented.

Testing and Reports

We are currently awaiting the results from the concrete testing, which are expected during the week commencing 26 June 2026. These results will be incorporated into the final CS470 report, enabling us to determine a long-term strategy for the structure.

Camera Installation

AI cameras have been procured for installation on the bridge. A purchase order has also been raised to connect power via the nearby lamp column.

A splitter will be installed to ensure:

  • Continued use of the column for Christmas lighting, and
  • A separate electrical feed for the camera system.

Enforcement

We are exploring options to introduce enforcement capabilities.

Surrounding Structures

WSP has been commissioned to undertake assessments of surrounding structures, to establish their current weight limits. This work is intended to provide a comprehensive understanding of the wider highway network.

Next Steps

  • Obtain a cost estimate for installing netting beneath the bridge
  • Explore the feasibility of creating new access to the structure, subject to landowner approval
  • Review the report findings to determine whether the removal of lighting is possible

Weight Limit Consultation

A proposal to increase the weight limit to 7.5 tonnes is currently under consultation. Follow this link to find out more: www.monmouthshire.gov.uk/amendment-order-no-19-2026/ (Closing date: 1 July 2026)

*One objection has been received to date. (26/06/2026)

Tap Test

Wren Works have been procured to undertake a tap survey of the beams beneath the carriageway.

  • Start date: 25 February 2026
  • Duration: Approximately 2 weeks
  • Traffic management: Full road closure during working hours
    • 09:00 – 15:30 (daytime closure)
      These closures are required to ensure the works can be carried out safely.

Drone Survey

Landscope have been commissioned to carry out a drone survey of the structure.
This will allow detailed inspection of cracking and provide a baseline condition record for any future monitoring or investigations.


Consultants

  • WSP continue to assess the structure with the objective of enabling a return to two‑lane operation and a 7.5t weight limit.
  • We are also engaging with a second consultancy to independently verify the results and methodology.

Traffic Management

Our Traffic team has been asked to investigate the following measures:

  • Introducing chicanes on the approach to the viaduct to slow vehicles.
  • Installing VMS (Variable Message Signs) in the village to alert overweight vehicles not to cross the viaduct and instead rejoin the A465.

Business Support

Our Regeneration team has met with local businesses to identify what assistance can be provided to support them during the ongoing restrictions.
