  1. Currently stuck in A40 traffic jam…towards monmouth…police sending traffic off at Abergavenny junction…I’m assuming crash

  2. Hello,

    There’s a new speed limit of 20 by the A40 – Hanger Lane. When was this put and when has this been in action from?

  3. I was hoping to drive into London near Marylebone and using the A40 Marylebone flyover this afternoon – please advise if is closed today as it was recently.
