The duration of each closure would vary depending on the nature of the maintenance work being undertaken on each occasion. The programme of works would start on or after 1 st January 2021. The overnight closures would be in operation between 20:00 and 06:00 (maximum period).
Planned maintenance work would be scheduled to avoid disruption during known peak periods, although essential maintenance may be necessary during these periods to prevent the need for emergency works. In such cases less disruptive options would be considered. The Order would come into force on 1 st January 2021 and shall remain in force until 24th December 2021.
During the closures, traffic affected would be diverted using other junctions of the A23 and A27, or by using the M25, A22, A24, A27, A29, A259, A264, A270, A272, A281, A283, A284, A293, A2011, A2038, A2270, A2280, A2300, B2036, B2110, B2114, B2115, B2117, B2118, and various local roads. The diversion routes listed above are the agreed routes, but these may change depending on local conditions. The diversion in operation would vary according to the closure in force.
Access to and from premises accessible from, and only from, the lengths of carriageway to be closed would be permitted under escort. The temporary lay-by closures, bus stop closures, side road closures, slip road, carriageway closures and diversion routes would be clearly indicated by traffic signs when they are in operation during the works periods.
