A2300 corridor improvements scheme

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

(Position at October 2020)

Latest update

We will be closing the section of Cuckfield Road between the A2300 roundabout and Goddards Green Wastewater Treatment Works to all traffic from 8.00pm on Friday 23 October to 5.00am on Monday 26 October. This closure is to allow us to install a drainage system. A signed diversion route shall be in place.

The current ‘exit only’ arrangement at Bishopstone Lane/Jobs Lane/A2300 junction has been extended until 30 November 2020. This is to enable the installation of a drainage system and ducting.

Works completed this week:

Phase 2 - A2300 Main Line

  • Ongoing installation of new drainage system.
  • Ongoing installation and backfilling of the attenuation tanks.
  • Installation of ducting and drainage across Bishopstone Lane.
  • Installation of ducting for telecom and water diversions.
  • Ongoing installation of communication ducting.
  • Continue with backfilling of new gabion wall.
  • Completed vegetation clearance (between Bishopstone Lane and Cuckfield Road). This is the last of the vegetation clearance in Phase 2.

Works planned for week commencing 26 October:

Phase 2 - A2300 Main Line

  • Continue ongoing installation of new drainage system.
  • Drainage installation at Cuckfield Road roundabout.
  • Ongoing backfilling of the attenuation tanks.
  • Ongoing installation of new communication ducting.
  • Construction of new road box.

Further updates on works progress will be provided here.


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.

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, developer’s contributions and WSCC.

Public engagement

A public engagement was completed in autumn 2018.
