M3 J9 Upgrade Update 2026 | New Road Layout A3S-M3S & South facing Overlay & Construction Progress

A detailed drone flight over the M3 Junction 9 improvement scheme near Winchester, focusing on the new A34 southbound to M3 southbound direct link and the significant changes taking shape across the junction. Using aerial footage with a road layout overlay, this video shows how the future road network will operate and highlights one of the most important elements of the project: the new free-flow connection allowing traffic travelling from the A34 southbound to join the M3 southbound without negotiating the existing roundabout. Looking south across the works area, you can see the scale of the earthworks, new carriageway construction, bridge structures and alignment changes that will eventually transform one of the South of England's busiest strategic road junctions. The M3 Junction 9 scheme is designed to improve traffic flow, reduce congestion and enhance safety at the key intersection of the M3, A34 and A33. The route serves long-distance traffic between the Midlands, South Coast, Southampton, Winchester and London, making it a critical part of England's strategic road network. 📍 Location: Winchester, Hampshire, UK 🎥 Filmed from the air to document construction progress and visualise the future layout of the junction.
