Operation Brock will be brought back when needed, instead of coming to a complete end this October.
The Department for Transport tonight confirmed that its sunset clause (expiry date) is removed.
This means that it can be brought back on the M20 if there is any further disruption on the port-bound corridor.
But a DfT spokesman stressed: “Operation Brock measures will remain temporary and will only be used when there is a significant risk of delays.
“It was originally created to deal with disruption caused by EU Exit and in response to the COVID-19 pandemic.
“Removing the sunset clauses from Operation Brock will mean the Kent Resilience Forum (KRF) is better prepared to respond to any type of traffic disruption in the area, not solely related to EU Exit, including strikes and severe weather.”
The traffic management system is a contraflow, which features narrowed lanes and a 50mph speed limit between Ashford and Maidstone.
It was last introduced for two weeks on July 18 in anticipation of increased international travel as a result of Covid restrictions lifting.
It had been extended to allow for feared traffic chaos after the UK completely left the European Union, following a transition period, which ended last New Year’s Eve.
It was also needed when roads to Dover ended up gridlocked just before Christmas when the French closed their borders.
It was a drastic precaution against a new strain of coronavirus getting into their country.
The DfT explains that although Operation Brock may temporarily affect Kent roads with reduced speeds, the measures minimise disruption to HGV drivers going abroad as well as other road users.
Its use remains temporary and only if seriously needed.
