Up and coming M4 closure weekend of the 21st - 24th March
South Gloucestershire Council - 17th March 2025
You may be aware National Highways will be closing the M4. This will affect our network.
Road: M4 between junction 18 and 19 in both directions
When: evening of Friday 21st March and reopening the morning of Monday 24th March
The closure by National Highways is to complete the demolition of the bridge.
National Highways will be using Vehicle Messaging Signs (VMS) at key locations. The VMS will warn road users that certain routes are not suitable and encourage them to use the official diversion. We will be supplementing this with our own signs to advise motorists, particularly HGVs, not to use certain routes as we did during the closure last October.
The National Highways full press release, that includes a link to the diversion route can be found via the following link:
A432 Badminton Road bridge crossing the M4 - National Highways
National Highways contact point during the road works for the public is as follows, and we have a team of engineers to be on standby over the weekend.
