M3 junction 9 improvements
We’re proposing to change junction 9, so it has free-flowing links between the M3 and the A34 both northbound and southbound.
Project information
The M3 connects south Hampshire with London, the Midlands and the North. It is also part of a key freight route. Roughly 6,000 vehicles an hour go through junction 9 during peak periods and traffic is particularly heavy between the M3 and the A34, with frequent queues on the northbound off-slip of the M3 which are a safety risk. At the moment we reduce the queues by allocating more time on green at the traffic lights on the northbound off-slip of the M3 and the A34 link. This amended sequencing, in turn, causes lengthy queues on the A272 Spitfire Link and Easton Lane. Overall the junction creates a bottleneck and significant delays.
The new proposed layout for the junction aims to:
- Improve safety by reducing queuing and delays
- Reduce congestion and improve journey times
- Reduce the number of people affected by noise and improve air quality
- Improve conditions for non-motorised users – a new cycle path would connect with National Cycle Network Route 23 which is severed by the current layout
- Support economic growth – improving road capacity which will help create jobs, improve business and support the building of new homes
The changes we’re proposing would reduce congestion at the junction and help make journey times more reliable. With less congestion there would also be fewer accidents and better air quality.
