M3 Junction 9 Drone Update | Two Weeks Before July Closure | Aerial Progress by drone

This 4K drone update captures the M3 Junction 9 improvement works just two weeks before the major July 2026 closure, showing how the site is evolving as National Highways prepares for the next phase of the upgrade. From above, you can clearly see the new roundabout formation, bridge deck works, earthworks, and the shaping of the future free‑flow A34 link. 🚧 Project Background — What’s Changing at M3 J9 The £268m–£322m National Highways upgrade is transforming this critical interchange between the M3 and A34, improving long‑distance freight routes and reducing congestion for Winchester and Hampshire drivers. Key elements include: • Construction of two new bridges forming the future roundabout alignment • Increasing the M3 from two lanes to four beneath the junction • Building a dedicated A34 northbound free‑flow link • Major drainage, earthworks, and slip‑road reconfiguration • Long‑term traffic management phases running into 2027 📅 July 2026 Closures — What’s Coming The footage is filmed just ahead of the first major weekend closure: • 31 July – 3 August 2026: Roundabout and slip roads closed; M3 mainline remains open • 21–24 August 2026: Second weekend closure • 11–14 September 2026: Third weekend closure • Northbound entry slip road closed long‑term until winter 2027 These closures allow crews to connect the new bridges, complete structural works, and switch traffic onto new alignments. 📡 What This Drone Video Shows • Current bridge deck progress and steel beam installation zones • Excavation and shaping of the A34 underpass approaches • New temporary traffic layouts and narrowed running lanes • Earthworks, drainage channels, and barrier installations • The wider transformation of the junction as it approaches a major milestone 🎥 About the Channel — A View Through The Lens I document major UK infrastructure projects using drones, 360° cameras, and in‑car footage.
