	From the start of July 2018 works have been taking place to upgrade a part of the M23 to an all-lane-running motorway. This is between junction 8, with the M25 and junction 10 with the A264. It is due to be finished by Spring 2020 with a budget of £164 million. The upgrades are taking place mostly for more reliable journeys to Gatwick Airport. The upgrades include an all-lane-running motorway, 12 new emergency areas, a new concrete central barrier replacing the current steel one, new roadside sound barriers, variable speed limits and two new emergency access slip roads.
