Protesters calling for the Calais migrant "Jungle" camp to be demolished have said they will not end their blockade "until we hear from the government".
Two convoys consisting of hundreds of tractors and lorries met on the main motorway, the A16, at the junction with the Channel Tunnel terminal today and, along with protesters on foot, have now settled in and refused to move.
Antoine Ravisse, president of a coalition of Calais businesses, said they want to make the roads in the area safe again.
He said: "It's unacceptable that today in France you can't travel without fear and without the certainty that you won't be attacked."
He added: "We are standing here and we will wait until we hear something back from the government."
A blockade of lorries and tractors held up traffic on the roads around Calais with a "go slow" protest against the "Jungle" migrant camp.
A convoy of trucks and tractors set off from Dunkirk to the north, while another made its way from Boulogne to the south at 7.30am local time on the A16, which runs along the edge of the town.
They are set to converge near the entrance to the Channel Tunnel and ferry terminals.
No traffic was being allowed to pass the blockade and police were stationed at the junctions, apparently to stop vehicles joining the motorway.
Hundreds of protesters also marched on foot along the road leading directly to the port.
Protesters have been gathering in Calais this morning ahead of a planned demonstration against the "Jungle" migrant camp.
British cross-Channel travellers have been warned they face major disruption as French shopkeepers, police, unionists and farmers join hauliers in calling for the northern section of the camp to be demolished.
A trade association has warned drivers will stand their ground until they see action to dismantle the camp.

Dozens of people have been injured - eight seriously - after a packed passenger train collided with a fallen tree at 85mph in southern France.
Carriages were strewn with debris while the front of the train crumpled in the collision, which happened around 3.45pm near Montpellier.
The tree had fallen across the tracks in a torrential hail storm before the train, carrying 200 passengers, came down the line.
Paramedics treated 50 people for minor injuries, while at least one of the more seriously injured was flown to hospital by helicopter.
Local media said initial reports the train derailed in the crash were unfounded.
