Plans to erect metal barriers on the M20 in the event of a no-deal Brexit have been permanently scrapped.

Their role was to separate HGVs on one side of the motorway heading to cross-Channel ports, with all other traffic restricted to a contraflow system.

Instead moveable concrete barriers can be installed within hours.

Compared to the speed restrictions and month-long overnight motorway closures required for Operation Brock, the new scheme causes less disruption to traffic and would be on standby from later this year, Highways England said.

It is designed to ensure the M20 is kept open at times of disruption, while also allowing the motorway to retain three lanes, a hard shoulder and 70mph speed limits in both directions during normal traffic conditions.

Transport Secretary Grant Shapps said: "After listening to frustrated residents and businesses affected by Operations Brock and Stack, we've invested in a new solution to boost Kent's resilience and keep its vital road network moving, even at times of disruption."

Highways England said the technology had been chosen by the Department for Transport and Highways England as a long-term solution to Operation Brock and Stack, and would ensure Kent was prepared for any disruption on the Short Strait, such as from industrial action or bad weather too.

The new solution also means that Highways England's work on an off-road replacement for Operation Stack has been halted. As part of this, previous Highways England plans for a new large lorry holding area in Kent are no longer being pursued.
