A2300 corridor improvements scheme

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

(Position at July 2020)

Latest update

The three consecutive night closures of the A2300 started on Wednesday 1 July till Friday 3 July. The closure will be from 8.00pm to 5.00am to allow us to carry out works to Virgin Media’s communications cables. The diversion route is the same as the previous closures and it is signed.

Advanced notice of the A2300/Stairbridge Lane junction closures:

We are planning to start a series of weekend closures at the southern end of Stairbridge Lane from Friday 17 July until the end of August. Each weekend the A2300/Stairbridge Lane junction will be closed to all traffic from 8.00pm on Friday evening through to 5.00am on Monday morning. The diversion route will be by Jobs Lane and it will be signed.

The access from the A2300 to Stairbridge Lane will be fully closed throughout September. However, traffic wishing to join the A2300 from Stairbridge Lane will still be able to do so.

These closures are required to allow the A2300/Stairbridge Lane junction to be reconfigured for the new dual carriageway.

Works completed this week:

Sportsman Pub on Cuckfield Road

  • The surfacing was completed on 29 June and road markings will be completed on Friday 3 July night for operational reasons.
  • Cuckfield Road between the A2300 and Gatehouse Lane will be closed overnight on Friday 3 July from 8.00pm to 5.00am. A signed diversion route via Jane Murray Way shall be in place.

Bolney Grange on Stairbridge Lane

  • The surfacing and road markings were completed on Tuesday 30 June.

Phase 2 - A2300 Main Line

  • Installation of Virgin Media’s duct across existing the A2300.
  • Our bulk earthworks have commenced this week and these shall be ongoing through the summer and early autumn months. The works involve cutting and filling the existing ground as part of the process to form the new eastbound carriageway towards Burgess Hill.

Works planned for week commencing 6 July:

Phase 2 - A2300 Main Line

  • Continue with the installation of Virgin Media’s duct.
  • Continue with the bulk earthworks.
  • Clear vegetation growth from the balancing pond.

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.
