A24 Robin Hood junction improvement

Details of the design and construction of the A24 Robin Hood junction improvements.

(Position at October 2020)

Background

West of Horsham, south of Broadbridge Heath village, has seen a large expansion of housing since 2010.

Part of the planning approval of the housing included the developer providing funding for changes to the roundabout at A24 Robin Hood junction. This formed part of a formal planning agreement.

The junction is impacted by traffic congestion in the morning and evening peak hours. This will continue to increase as the development areas are built, and with the general increase in background traffic. West Sussex County Council (WSCC) appreciates that currently, with the COVID-19 restrictions, traffic flows have been artificially suppressed, but in the longer term they will increase again.

Proposed scheme

WSCC is responsible for the design and delivery of the junction improvement, which consists of:

  • widening of the A24 in the southbound direction from two lanes to four lanes
  • widening of the A24 in the northbound direction from two lanes to three lanes
  • widening of the exit from Warnham Road on to the roundabout
  • traffic signal control on the A24 approaches and on the Warnham Road, with traffic signal control on the roundabout
  • provision of a signalised 'Toucan' crossing across the Northbound exit of the A24 (towards A24 Great Daux)
  • improved footway and cycleway connection Warnham Road to Robin Hood Lane and the Public Right of Way.

Benefits

The scheme will provide benefits through:

  • providing increased road capacity at the junction to allow for increased traffic due to local developments and through traffic
  • the provision of traffic lights with sensors, which adjust signal timings according to queuing levels to help ease congestion, on signalled approaches (not Robin Hood Lane) will help manage flows in the peak and off-peak periods
  • new crossing facilities for pedestrians and cyclists linking Warnham Park and the Public Right of Way with Warnham Road via new Toucan crossings.

Public engagement

This was completed as part of the developer's planning application/permission during 2009 and 2010.

WSCC will be liaising with Horsham District Council and local parish councils on the most appropriate approaches for keeping residents and businesses up to date with the scheme’s progress.

This web page will be updated as milestones are reached and then, once construction works begin, weekly or fortnightly, depending on work progress. Advance notices of the start of works will be displayed around the junction and traffic management restrictions will also be published.

Local residents and businesses will be able to sign up to a weekly email update from the contractor, once the main construction works take place, by providing their email addresses. We will provide details about this on this web page in due course.

Programme

Landbuild Ltd have been appointed by WSCC and have started to undertake advanced vegetation clearance works, drainage investigations and remedials and utility investigations/diversions for completion due around the end of November 2020.

Traffic management for the scheme includes off peak lane closures on the A24 and off peak, single lane, traffic signals on Warnham Road. There will be a 50mph speed limit on these sections during the works. There will also be works between the A24 and Robin Hood Lane during the same period.

Advance notice signing were erected to advise road users of the planned works and updates on progress will be posted to this page.

The main junction improvement works is planned for mid-spring 2021. The completion date will be determined by the contractor, but it is expected to be around the end of 2021 or early in 2022. Tenders for this work have been issued by the County.
