Welcome to our winter newsletter.
We've been busy working in the central reservation between junctions 9 and 14 on the M3 installing a safer concrete barrier.
All the foundation and drainage work between the M27 and Eastleigh has been completed and the new barrier has started to go in...
 How is it made?
Each section is laid as we go along using a machine called a slipform paver.
The wet concrete gets poured onto a conveyor belt which feeds the mixture through a special mould. This mould is used to make the drainage section and the barrier itself.
This all happens within our safe working area and means we can keep the same number of lanes open without closing the road to lift large blocks of concrete into the central reservation.
Why aren't you always out working?
Concrete needs to set at the right temperature. If it’s too cold or wet, it can break or become weak after it has dried. In hot temperatures, moisture can evaporate too quickly and cause the concrete to break - although that's not been a problem for us just yet!
The weather has a big impact on the work we do, which is why we're not always able to get outside, especially if temperatures are below freezing or if it’s raining too much.
Why are we doing this work?
Concrete barriers are much stronger and safer than metal ones and significantly reduce the risk of vehicles crossing over from one carriageway to another if there's an accident. They are also virtually maintenance free and will last twice as long as normal metal barriers, with far less need for closures for routine repairs in the future.

Further up the M3 near Winchester, our proposed improvements at junction 9 have moved forward to the next stage. Our Development Consent Order application was accepted for examination by the Planning Inspectorate on 15 December 2022.
We’re hoping to improve junction 9 so that it has free-flowing links between the A34 and the motorway.

The Red X sign tells you when a lane is closed. This helps protect drivers and their passengers who may have got into difficulty. It also provides a safe place to work for the emergency services, recovery operators and our road workers.
 It’s illegal and dangerous to drive in a Red X lane. If you’re caught, you could receive a fixed penalty of up to £100 and three points, and in some cases more severe penalties or a court appearance.
