We are holding a series of public information exhibitions, where you can learn more about smart motorways, see our proposals for junctions 8 to 10 and ask the project team questions:
|29 Sept 2017||3pm to 9pm||South Terminal Arrivals (Level 2) Gatwick Airport, West Sussex, RH6 0NP.|
|30 Sept 2017||10am to 5pm||South Terminal Arrivals (Level 2) Gatwick Airport, West Sussex, RH6 0NP.|
|6 October 2017||3pm to 9pm||Nutfield Lodge, Nutfield Road, Redhill, Surrey, RH1 4ED.|
|7 October 2017||10am to 4pm||Nutfield Lodge, Nutfield Road, Redhill, Surrey, RH1 4ED.|
Attendees to the exhibition at Gatwick are entitled to 2 hours free parking in the South Terminal long-stay car park. Disabled drivers should park in the short-stay and speak to the exhibition team to avoid charges.
For more information on travelling to and from Gatwick airport, visit their website.
Once we have worked up our proposed design we will invite you to our public information exhibitions. You will be able to learn more about smart motorways, our plans for the M23 in particular, and meet members of the project teams. We hope to do this in September 2017.
Why we need this scheme
The M23 is a crucial part of the UK strategic road network connecting Crawley and Gatwick Airport to the M25 motorway, routes into London and the rest of the UK.
This stretch of the M23 is heavily used by traffic travelling to and from Gatwick Airport and between Brighton and London, especially during UK holiday periods. As a result safety, congestion and journey times are all key issues that need to be improved.
As junction 9 of the M23 is the main access for traffic travelling to and from Gatwick Airport, this scheme is of particular local and national economic and political importance.
With this scheme, we aim to improve:
- journey times

The scheme in detail
The M23 junction 8 to 10 smart motorway scheme will add further road space by converting the hard shoulder to a permanent running lane with additional traffic monitoring, emergency refuge areas and variable message signs. The work will include:
- four permanent running lanes in each direction, created by conversion of the hard shoulder
- redefined junction layouts to accommodate the extra lane
- 16 new gantries to carry the new variable message signs
- 11 new emergency refuge areas
- a hardened central reserve with a new rigid concrete barrier
- new noise barriers where identified by environmental assessment
- work to maintain access to the motorway from Weatherhill Depot and for traffic officers
During the construction phase of the scheme, roadworks will be needed along this section of the M23 between junctions 8 and 10. It is anticipated that narrow lanes traffic management, temporary concrete safety barriers and speed restrictions will be put in place. In addition junction layouts may be temporarily altered to allow for resurfacing and improvement.
There will be temporary closures of the carriageways at night on some occasions. In these instances all updates and diversions will be clearly available and published in the appropriate section of the scheme’s webpage. Clearly signed diversions will be put in place where the work is being carried out.
Highways England is committed to delivering better environmental outcomes. In remaining within current motorway boundaries, smart motorways have the built-in advantage of minimising scheme environmental footprints. In addition, we carry out thorough environmental assessments to identify and assess potential environmental impacts and recommend mitigation that can be included in the scheme to minimise them.
M23 junction 8 to 10 environmental assessment
We have considered the full range of environmental topics and found that there will be no long term significant effects. Temporary effects during construction will be slight changes in views, construction noise, disruption to road users and some loss of habitat of negligible value. A comprehensive Construction Environment Management Plan will minimise these effects.
The key issues considered are:
- air quality, noise and visual impacts in relation to nearby housing
- the SSSI between Mole Gate and Reigate Escarpment
- protected species and habitats including bats, badgers and great crested newts
- the setting of conservation areas and heritage assets such as Surrey Hills Area of Outstanding Natural Beauty
- public rights of Way
