Public Exhibition to find out more about the M23 Junctions 8 to 10 Smart Motorway

Work is to start in March 2018 on the M23 between Junctions 8 and 10, connecting Crawley and Gatwick Airport, to convert this section into a smart motorway, this includes converting the hard shoulder into a permanently running lane and introducing variable mandatory speed limits along this section of the motorway to help improve traffic flow.

The smart motorway is being designed to smooth traffic flow, increase capacity and make journey times more reliable by using variable speed limits, new signals and signing. The work will involve the use of technology and the conversion of the hard shoulder into a permanent live lane, known as an All-Lane Running smart motorway.

The programme is scheduled to start in March 2018 and will be completed by January 2020. You can track progress on the website.

The M23 will be affected at various times during the construction phase of the project. During the construction phase, narrow lanes will be required to create a safe working space. Lane and full carriageway closures will also be required during the construction of the project. Full diversion routes will be clearly signed during these closures. Specific details will be sent to you and made available to the public, before construction starts. Details will also be available on the website.

They are currently organising Public Information Exhibitions (PIEs), where you will be able to learn more about Smart Motorways, their plans for the M23 in particular, and meet members of the project teams.
