there are terrible traffic queues at m4 jct 8 , not reported on the camera or this website now 17.08 04/03/25
Please could I have a list of traffic accidents and congestion on the m4 in wales to Bristol prior to 1pm on Sat 19/10/24? I need it for insurance purposes, as I missed a flight. Thank you.
I was travelling back on the M4 on Sunday afternoon, after visiting my daughter’s family.
What I want to know is, why didn’t highways team place diversion signage at jnct 13, i.e. BEFORE arriving at Jnct 12.
The nightmare that I was stuck in lasted 5 hours… to go 8 junctions along the M4.
Being in that kind of traffic where you travel at 3 mph for almost 5 hours is not economical, healthy, sensible nor effective.
Whoever thought it was ok to plan it so everyone fell foul of the traffic backlog should lose their job.
I felt like I had jetlag this morning…
Will M4 be closed at Pontabraham on Sunday 3rd September.Also what other roadworks the same day on M4.
On Saturday 19 March at approx midnight, I will drive from London to Windsor on the M4 hoping to exit at junction 6 for Windsor. Will I be able to do this smoothly or will there be deviations on my way to Windsor from London for M4 works on Saturday the 19th of March? Thanks
Will M4 be open, right through from Wales to Heathrow, Friday night to early sat morning, flight to catch
Hi
Please can you confirm is there a diversion set up just before junction 8/9 of the M4 as I need to get on the M4 to travel to Somerset.
please can you put closures on M4 as I have to give news to my hubby who, at present, is driving a coach between Cardiff to Heathrow, or London Victoria or Bristol Airport. Your website is atrocious at trying to find out what is closed, when its closed and its opening hours. We need it in plain speak please to make professional drivers less tense and able to work out if they have to divert.
IS THE ROUNDABOUT STILL CLOSED AT JUNCTION 13 ON M4
M4 5 miles traffic due to a car crash
Thank you for your live update, really useful to know.
