The unpopular measure has been introduced yet again due to an expected increase in road traffic.
In a press release, National Highways has confirmed the M20 will be closed as follows:
- 9pm Tuesday 11 July to 6am Wednesday 12 July: Coast bound carriageway between junction 9 and junction 8
- 8pm Thursday 13 July to 6am Friday 14 July: London bound carriageway between junction 9 and junction 8, coast bound carriageway between junction 7 and junction 9
Fully signed diversion routes will be place while the M20 is closed overnight.
When the M20 reopens at 6am on Friday 14 July, the Operation Brock contraflow will be in place and all signs and signals should be followed.
National Highways says these times have been chosen to minimise disruption to road users.
Once the barrier is in place, all HGVs heading for the Port of Dover or Eurotunnel must follow the signs to join Operation Brock at M20 junction 8.
“Any EU-bound HGVs not complying with signage and trying to use another route to Eurotunnel or the Port of Dover risk a fine of £300. They will also be sent to the back of the queue by Police or enforcement agents, wasting time, fuel, and money. This includes trying to bypass the M20 by using the M2/A2 at Brenley Corner,” warns National Highways.
The roads authority states that other coast bound traffic – including local freight and car drivers heading for the continent – should follow the signs and cross over to enter the contraflow on the M20 London bound carriageway.
Commenting on the return of Operation Brock, Sean Martell, National Highways Head of Service Delivery, said:
“Ensuring the smooth flow of traffic through Kent is a top priority and we, along with our fellow Kent Resilience Forum partners, have taken the joint decision to activate the Operation Brock contraflow ahead of the summer holidays. While we understand this won’t be welcome news for some, the decision was made taking several factors into consideration, including expected high passenger numbers, particularly coaches. The crucial thing about the contraflow system is that it keeps Kent open and traffic moving in all but the most extreme circumstances.”
National Highways has advised motorists to be prepared for delays by having plenty of fuel, as well as warm clothes and supplies such as food and drink. The contraflow is expected to be in place for two weeks.
