Preliminary work ahead of a new signalised junction at the A251/A2 junction in Faversham will begin on Tuesday (April 6).
It comes as part of plans by Kent County Council to ease congestion and queuing on the A251 Ashford Road and improve turning onto the A2 Canterbury Road.
Before work can start on the scheme, which will include pedestrian crossings and widening the A251, there are several underground utilities that need to be changed.
The utility work may take up to 11 weeks to complete and as a result traffic will be controlled by closing the A251 Ashford Road between the Aldi roundabout and the A2 Canterbury Road.
The closure will be in place for 24 hours and seven days a week until the utilities work is complete.
There will also be temporary traffic signals on the A2 Canterbury Road during the working day between 8am and 3.30pm.
The diversion route for the road closure will be via the M2 and Brenley Corner roundabout.
Traffic management operatives will be on hand throughout the day and will allow residents and businesses within the closed area, as well as vehicles not permitted on the motorway, through the closure.
The roadworks are not connected to the traffic management plan introduced following the end of the EU transition period, which currently requires all HGVs accessing Kent ports to join Operation Brock on the M20.
HGVs are therefore not permitted to access the Port of Dover via the M2/A2, and over the last 24 hours Kent Police officers stationed at Brenley Corner have turned around more than 350 HGVs that should not have been travelling there.
This traffic management will be removed tonight (Thursday) but enforcement activity will continue using alternative policing methods.
Highways England is advising drivers making essential journeys in Kent, this weekend to plan ahead as closures will be in place on parts of the M20.
From Highways England: M20 – overnight closure
The M20 section between junction 9, for Ashford, and junction 8, for Maidstone, will be closed for London-bound traffic from 10pm – 6am on Saturday 3 April while barrier maintenance and carriageway repairs are carried out.
London bound traffic (except for HGV’s over 15ft 6” (4.7m)) will be diverted to follow the A20. Motorists and motorcyclists should exit at junction 9 onto the A20 and continue westbound on the A20 to junction 8 where they will be able to re-join the M20.
A low bridge at Harrietsham which has a height restriction of 15ft 6” (4.7m) means that vehicles over this height should follow alternative signed diversion routes.
The coast bound carriageway will remain open and all port bound freight using the Port of Dover or Eurotunnel are reminded to use the Operation Brock M20 lorry holding area. Eurotunnel freight should join the queue in lane 1, with Port of Dover hauliers joining the queue in lane 4.
From 6am Sunday 4 April all coast bound freight heading through Operation Brock will proceed through the freight area and will no longer be held at the front of queue by the barrier.
