Overview
- Eastbound M4 in Cardiff was closed between J33 and J32 after a multi‑vehicle crash, with Traffic Wales reporting severe queues and South Wales Police warning the road would stay shut for some time.
- A separate multi‑vehicle collision on the M25 anti‑clockwise between J17 (Rickmansworth) and J16 (M40) closed lanes 3 and 4 early Wednesday, prompting delays exceeding 90 minutes and heavy congestion on approaches.
- On Tuesday evening, three lanes of the M62 eastbound shut between J11 (Birchwood) and J12 (Eccles) after a multi‑vehicle crash, with 90‑minute delays reported before all lanes later reopened; a westbound crash near Huddersfield on Wednesday also caused residual delays after traffic was held.
- Overnight on the M1 near Milton Keynes, a serious crash closed multiple lanes between J13 and J15, with National Highways estimating normal flow would resume around 3:45am as crews worked at the scene.
- Separately, authorities confirmed two full‑weekend M6 closures in January between J39 and J40 for Network Rail’s Clifton Bridge replacement, and detailed a longer Lune gorge programme including contraflow, 30mph limits and an 18‑months‑each closure of Tebay’s J38 opposed by local campaigners.
