Hampshire County Council Proposals are for the Brighton Hill roundabout to be widened to 4 lanes.
There will be no entry onto the roundabout from Western Way and traffic lights on all 5 remaining entries, underpasses to be retained, and new crossings with the traffic lights.
A public consultation is going live on Sept 3rd and will run until October 1st.
The preferred scheme will then be agreed in November, with a submission for funding in December with a view to securing the provisional £18.6m set aside to cover the scheme and initial work on other improvements further down the A30 towards Kempshott, Hatch Warren and the M3. Work is expected to start in 2020.
I will publish more details once the consultation is live.
