The A2300 links Burgess Hill to the A23/M23 strategic road corridor and is an important route for people commuting to and from Burgess Hill.

In 2011, Mid Sussex District Council’s Transport Study identified that the A2300 would require improvements to increase its capacity to support the planned development in Burgess Hill. West Sussex County Council (WSCC) subsequently commissioned a feasibility study to explore possible improvement options.

Coast to Capital Local Enterprise Partnership (C2C LEP) identified Burgess Hill as a priority in its 2014 Strategic Economic Plan with the objective of generating economic growth through housing and employment.

£17m has recently been approved by central government through the C2CLEP Local Growth Deal as a contribution to the A2300 corridor improvements scheme. WSCC is the scheme promoter and responsible for delivering the scheme.

Proposed scheme

The proposed scheme, based on the outcomes of the options assessment process, traffic forecasting and economic assessment, is the upgrade of the existing single carriageway road to a dual carriageway between the A23 and the proposed Northern Arc roundabout. It will involve the construction of a two-lane new carriageway immediately north of the existing road which will become the new eastbound carriageway. In addition, other changes will also be introduced, which will involve:

  • modifications to the existing carriageway to form the new westbound carriageway
  • modifications to the existing roundabouts with the A23 at Hickstead and Cuckfield Road to allow for the dualling
  • closure of the central reserve at the Pookbourne Lane/Stairbridge Lane junction and conversion to a ‘left-in/left-out’ arrangement
  • left-out only arrangement at Bishopstone Lane junction
  • a 2.5m-wide central reservation with vehicle restraint barrier
  • improvement to access arrangements on the south side of the A2300
  • associated surface water drainage, landscaping and planting measures.

The proposed scheme also provides opportunities for more journeys to be made by cycling and walking through the provision of:

  • a 3m-wide shared use footpath and cycle path on the north-side between the A23 and the proposed Northern Arc roundabout
  • a 2.5m-wide shared use footpath and cycle path on the south-side of the A2300 between the A23 and Pookbourne Lane/Stairbridge Lane junction and also between Bishopstone Lane and Cuckfield Road roundabout.
