Latest updates

The aim of the scheme is to reduce traffic congestion in the area and create a  new link road between Western Way and A30 Winchester Road, through the Camrose site. A planning application for this element of the project will be submitted.  Main works are scheduled to begin in 2020.  Please view the latest press release here.

Scheme overview

The A30 South West (SW) Corridor provides an important link between the M3 Junction 7 and Basingstoke Town Centre, serving existing communities in South Ham, Brighton Hill, Kempshott and Hatch Warren. A number of new housing developments are proposed or being implemented at along the corridor, at locations identified in the Adopted Local Plan. These will increase travel demand in future years.

The County Council has provisionally secured £13.0 million of Local Growth Deal funding from the Enterprise M3 Local Enterprise Partnership for improvements to the A30 SW Corridor. This matched by £5.6 million of funding from the County Council, primarily financial contributions from new developments, giving a total budget of £18.6m. This funding will be used to implement proposals that address existing and future congestion problems along the corridor.

The County Council has commissioned feasibility work to identify preferred improvements to Brighton Hill Roundabout. In the short term, further work will be undertaken to identify preferred improvements to Kempshott Roundabout and the County Council is seeking funding to examine further improvement that would be required for the A30 SW Corridor.
