Plans are underway to upgrade parts of the M23 to an all lane smart motorway.  

The proposals are for an 11 mile stretch of the M23 near Gatwick Airport between junction 8 near Merstham and junction 10 at Copthorne. The 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. Highways England say the scheme is of local and national importance due to junction 9 being the main access road to and from Gatwick, and as a result safety, congestion and journey times are all key issues that need to be improved.

During the construction phase of the scheme roadworks will be needed on the M23 between junctions 8 and 10 with narrow lanes.  

Public information exhibitions will be held on 29th and 30th September from 3 pm until 9 pm at Gatwick’s South Terminal arrivals on Level 2, and on 6th and 7th October at Nutfield Lodge also from 3 pm -9 pm.
