The M48 westbound carriageway between junctions 1 and 2 will be shut from 8pm today, August 6, until 6am tomorrow for planned maintenance. The Severn Bridge is a key transport link between South Wales and England, carrying commuters, freight, and holiday traffic across the River Severn. Motorists travelling westbound towards Monmouthshire and Newport are being advised to allow extra time for their journeys and check traffic updates before setting off. Those travelling overnight between South Wales and England are advised to check the latest travel information and allow additional time where needed. Full details of planned roadworks and closures are available on the National Highways travel updates service.
