New M3 J9 Winnall Slip Road Layout – Post‑Closure Drive‑Through

Описание: Join me for an in‑car drive‑through of the new Winnall slip road layout at M3 Junction 9, filmed just after last weekend’s full roundabout closure. This video shows the updated southbound off‑slip, the revised gyratory geometry, and how traffic now flows through the upgraded interchange following the latest construction phase.

The M3 Junction 9 Improvement Scheme, delivered by National Highways, is one of the South East’s most significant road upgrades. The project is transforming the connection between the M3 and A34, improving journey reliability, reducing congestion, and supporting major housing and economic growth across Winchester and the wider Hampshire region.

🔧 What’s New After the Weekend Closure

Recent closures allowed engineers to:

• Connect new slip road alignments to the existing network
• Bring the new roundabout bridge into public use
• Install and surface the new M3 southbound off‑slip
• Reconfigure the gyratory layout for future traffic phases
• Complete structural works on the north and south bridge decks
• Advance preparations for the new A34 northbound free‑flow link
These changes are part of a wider programme that will eventually increase the M3 from two lanes to four beneath the junction and create free‑flowing links between the M3 and A34 in both directions.

📍 Local Context – Winchester & Winnall

The junction sits at the gateway to Winchester, connecting:

• Winnall Industrial Estate
• Easton Lane
• A33 and A272 Spitfire Link
• Key commuter routes into the city centre
The upgrade is essential to support 2,000 new homes planned for Winchester and to improve freight movement between Southampton/Portsmouth and the Midlands.
