Drivers are advised to plan ahead as the final phase of work to create a free-flowing motorway with a 70mph speed limit on the M48 Severn Bridge is currently under way. Various closures are taking place this coming weekend 21-24 June 2019:

  • The M48 bridge (J1-2) will be totally closed in both directions from 11pm Friday 21 June 2019 to 6am on Monday 24 June 2019
  • The M48 westbound from the M4 J21 to M48 J1 will be closed from 11pm Friday 21 June 2019 to 6am on Monday 24 June 2019

Drivers are asked to use the M4 Prince of Wales Bridge as an alternative route.
For access to Aust, drivers will be asked to use the M5 J18 at Avonmouth and the A403.
A diversion route map for the M48 closure can be downloaded here..

We also want customers to be aware that the M49 will be closed for the weekend.
A giant 500-tonne crane will be used to lift a new bridge into place over the weekend (21-24 June) as part of work to create a new elevated junction on the M49 and a much-needed connection into the Avonmouth and Severnside Enterprise Area from the motorway network.
The M49 will be closed for the weekend, from 8pm on Friday, 21 June to 6am on Monday, 24 June, to enable this key part of the project, which will see bridge beams, decking and other infrastructure lifted into place immediately next to the existing bridge at Farm Lane.

While the M48 Severn Bridge is closed this weekend, Highways England will also be taking the opportunity to carry out essential maintenance work with teams working on opposite sides of the carriageway each night to fully utilise the closures and get as much done as possible.
Overnight closures for alternate carriageways are also planned between 24 June and 6 July while this maintenance work is completed. This should avoid further closures for maintenance in future.

Highways England’s traffic officers will be monitoring traffic flows from the Regional Operations Centre and advising drivers via signage where necessary. Work on the M4 Prince of Wales bridge was completed at the end of May and it has already been returned to a 70mph motorway. We always aim to work to the programme, however unforeseen circumstances or adverse weather conditions may mean changes to it. Please monitor www.trafficengland.com to keep up to date, as well as following us on Twitter @HighwaysSWEST. We will make every effort to ensure the impact on the local community and travelling public is kept to an absolute minimum. If you have any queries or comments about the work, or would like further information please contact the Highways England Customer Contact Centre on 0300 123 5000 or by email: [email protected]
