National Highways and regional police traffic incident logs confirm previous carriageway closures and lane restrictions along this corridor have completed safely:
The M5 motorway spans 162 miles (261 km) from the Ray Hall Interchange (M6 J8) in West Bromwich near Birmingham to Junction 31 south of Exeter, where it bifurcates into the A38 and A30 trunk roads into Devon and Cornwall. It serves as the irreplaceable commercial and tourism lifeline for the West Midlands, Worcestershire, Gloucestershire, Bristol, Somerset, and Devon.
Key engineering milestones include the Almondsbury Interchange (M4/M5 J15/J16)—the UK’s first four-level motorway stack interchange—and the 1,388-metre Avonmouth Bridge carrying eight lanes of traffic over the River Avon at Bristol.
The Avonmouth Bridge features complex acoustic expansion joints and active structural wind monitoring. Precautionary lane restrictions or reduced speed limits (50 mph) are deployed during high winds or expansion joint maintenance.
Summer weekend holiday departures generate unprecedented vehicle density. Southbound flows through Somerset (Junctions 20 to 25) routinely exceed design capacity, causing stop-start conditions that elevate secondary rear-end collision risks.
Official DfT STATS19 casualty statistics confirm 2,150 collisions on the M5 over 5 years, resulting in 48 fatalities and 380 serious casualties. The vast majority of incidents occur between Junctions 14 (Thornbury) and 20 (Clevedon), reflecting dense commuter merging around Bristol.
Wet road conditions contributed to 33.5% of collisions, highlighting the operational challenge of rapid cloudburst rain off the Bristol Channel.
In the event of complete carriageway closure on the M5, traffic is diverted onto established Emergency Diversion Routes. North of Bristol, traffic diverts via the A38 trunk road. For long-distance South West freight during major closures south of Bristol, traffic is advised to divert onto the A303/M3 corridor.
Essential guidance compiled from National Highways operational protocols, Police collision reporting procedures, and the UK Highway Code.
Yes. A single lane closure is active on the Avonmouth Bridge between J18 and J19 for structural maintenance, creating approximately 18 minutes of delay heading towards Somerset and Devon.
All carriageways are open, but three lanes out of four are operating across the Avonmouth crossing. Normal speeds resume south of Junction 19.
