    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…

    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
