A2300 corridor improvements scheme

Details of the development of the A2300 corridor improvements scheme in Burgess Hill.

(Position at September 2019)

Background

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 was allocated by central government through the C2CLEP Local Growth Deal as a contribution to the A2300 corridor improvements scheme, conditional on delivering the business case and value for money. 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 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 and:

  • 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 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 site access 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.

Scheme aim

The primary aim of the proposed scheme is to support delivery of the C2C’s Strategic Economic Plan and the Mid Sussex District Plan by enabling the delivery of new homes and jobs in Burgess Hill.

Scheme cost

The estimated cost for the proposed scheme is £23m and it is jointly funded by the Department for Transport, WSCC and developer’s contributions.

Public engagement

A public engagement was completed in autumn 2018.

Programme update

Advanced site preparation, including tree and vegetation clearance for the scheme will be undertaken from mid-September 2019 and is likely to take six to eight weeks to complete.

We are currently completing the preparation of the full business case for the scheme and this will be submitted to the Department for Transport in autumn for approval. It is anticipated the full business case will be approved later this year or early next year. This will enable the majority of the funding for the scheme to be secured.

The start date for the main construction works, which includes further site clearance, is dependent on the approval of the full business case. At present this is forecast to be spring 2020, with the works expected to take around 18 months to complete.

The scheme ties in with Homes England’s works for the proposed Northern Arc site access roundabout and we are working closely with Homes England to coordinate the delivery of the two schemes. Homes England has indicated that they aim to commence construction work in summer 2020, subject to approvals and contracts.
