Operation Stack caused huge delays as lorries backed onto M20 from Dover port
Scenes similar to the summer of 2015, when the M20 to Dover was turned into a huge car park with 20 mile tailbacks, could become the norm as border controls struggle to adapt to changes.
Operation Stack , which closes the motorway to the port of Dover during extremely busy times, was almost a daily occurence in Kent at the height of the Calais migrant crisis, as road and rail were blocked with burning tyres at the other end of the Channel.
The blocked roads severely interrupts traffic across the south east.
And Tim Waggott, the CEO of the port of Dover, warned a failure to make a new deal during Brexit negotiations could spark further disruption to Britain.

Dover already suffers from major road blockages on a regular basis
Imports and exports could be delayed for hours, stuck in huge tailbacks as border controls struggle to adapt to life outside the European Union.
Mr Waggott insisted stalled negotiations could drastically affect processes at Dover – which oversees 17 per cent of all traded goods arrive or leave through the port.
The EU's chief negotiator Michel Barnier has already highlighted customs checks as a potential obstacle to trade after the UK quits the Brussels bloc.

We will see [Operation Stack] every day of the year, in perpetuity, if we don't get this situation sorted

Dover already suffers from major road blockages on a regular basics, particularly during French industrial action and occasional bursts of bad weather in the English Channel.
And Mr Waggott warned the consequences would be felt nationwide, with jobs being lost up and down the country and retailers suffering massive losses.
He said: “The Armageddon scenario would be jobs being lost in the Midlands engine or the northern powerhouse.
Operation Stack lasted for an unprecedented 30-plus day
“In 2015 we saw Operation Stack in place for an unprecedented 30-plus days.
“We will see that every day of the year, in perpetuity, if we don't get this situation sorted."
For those who live even remotely near Dover, Operation Stack is not an option.
And long queues in Britain will also mean long queues in Northern France as lorries struggle to cross the Channel.

It would also be extremely costly for manufacturers and retailers, who rely on quick deliveries.
But Mr Waggott claimed he was confident another solution was available to avoid such massive tailbacks, and the devastating effect this could have on the UK economy.
He said: "The answer is some form of passport for goods, a technology-based solution that effectively gives us advanced information about what is moving from where, and to where."
He added: "Two years isn't a long time, IT systems take a long time to deliver. Certainly we will need some sort of transitional arrangement to make this work."
