M27 Junctions 4 to 11 – Update Update

To accommodate deep reconstruction activities on the M27 between junction 9 and 11, we will need to close alternate carriageways for an entire weekend. During this time, we’ll take the opportunity to undertake as many additional activities as possible.

The M27 westbound carriageway will be closed between junction 11 and 9 from 9.00pm 24 September 2021 until 6.00am 27 September 2021. We will then close the M27 eastbound carriageway between junction 9 and 11 from 9.00pm 1 October 2021 until 6.00am 4 October 2021. We are unable to complete this activity during a standard overnight closure, and as a result a full weekend closures is required on each carriageway. We will be alternating carriageways to ensure that one direction of travel is kept open at all times between junction 9 and 11.

All diversions will be clearly signposted, and details of the diversion routes are on the following page.

As is always the case, all dates are subject to change owing to operational requirements or adverse weather conditions. We therefore advise road users to plan their journeys in advance and keep up to date by visiting our Traffic England website: or by following our Twitter feed: @HighwaysSEAST.
