(b) a mandatory 24-hour 40mph speed limit on: -

(i)   the southbound carriageway of the

It is expected that the work would last for approximately 10 months starting on or after Monday 17th March 2025. Details would be found on the National Highways website. Overnight closures would take place between 20:00 and 06:00 (maximum period), for the purpose of setting up, changing, and removing the various configurations, during which the ERA would also be briefly closed.

The Order would come into force on 15th March 2025 and have a maximum duration of eighteen months, ceasing when the works are complete.

Traffic affected by the closures would be diverted by using the A23, A264, A2011, A2220, and B2036. The diversion would vary depending on the direction of closure.

The temporary closures, speed restrictions, lane width restrictions, and diversion routes would be clearly indicated by traffic signs when they are in operation during the works period.
