Severn Bridge M48 Temporary Heavy Vehicle Ban: What You Need to Know

Date of Implementation: 8th July 2025

The Welsh Government has announced a temporary ban on heavy vehicles over 7.5 tonnes on a section of the M48 motorway, specifically at the Severn Bridge in Monmouthshire. This decision aims to facilitate essential roadworks and ensure public safety by preventing potential hazards or damage to the road.

Key Points:

• Affected Area: The eastbound carriageway of the M48, from Junction 2 to 47 meters east of the western end of the Severn Bridge.
• Duration: The order is effective from 8th July 2025 and can last up to 18 months, although the temporary traffic signs' removal will mark the end of the works period.
• Exemptions: Emergency vehicles, maintenance vehicles, and those authorised by police or traffic officers are exempt from this restriction.
• Traffic Management: Alternative routes will be available, and appropriate signage will guide affected drivers.

This measure, enacted by the Welsh Ministers under the Road Traffic Regulation Act 1984, ensures that maintenance work can be carried out safely and efficiently, minimising risks to the public and infrastructure. Keep an eye out for traffic signs indicating when and where the restrictions apply.
