M20 Overnight Shutdown as Operation Brock Gets the Boot
Motorists brace yourself! The M20 faces a hefty overnight closure this Sunday as the controversial Operation Brock contraflow system is torn down once and for all.
What You Need to Know About the Closure
- The 13-mile stretch between Junction 8 (maidstone/" title="Maidstone" data-wpil-keyword-link="linked">Maidstone) and Junction 9 shuts from 8pm Sunday, August 17 until 6am Monday, August 18.
- London-bound carriageway closure: Junction 9 to Junction 8.
- Coastbound closure: Junction 7 to Junction 9.
- Fully signed diversion routes will guide drivers—avoid relying on sat-navs.
Once cleared, expect both carriageways to reopen with three lanes and the national speed limit restored.
Operation Brock: A Costly Traffic Nightmare
Introduced by the Kent and Medway Resilience Forum during summer holidays to manage looming port traffic chaos, Operation Brock sparked outrage. Residents and MPs slammed it as a “massive inconvenience” with many questioning why it runs every school break.
The system was meant to control HGV queues for the Port of Dover and Eurotunnel but racked up a hefty price tag.
- Costs around £250,000 each time it’s set up or dismantled.
- Maintenance runs at roughly £100,000 per week.
What’s Next? Digital Tech and Off-Road Lorry Holding Sites
National Highways says the overnight timing aims to keep disruption low. Meanwhile, the government is toying with a permanent fix involving smart digital traffic management and off-road lorry parks. But don’t hold your breath — that plan is still in its infancy.
For now, expect delays and diversions this weekend as Operation Brock bites the dust.
