10 people were arrested during a climate change protest close to the Port of Dover.
The campaign was organised by the group Extinction Rebellion and took place between 11am and 3pm. Protesters were told they could legally occupy a cordoned off area on Townwall Street close to the port.
Kent Police said officers closed the A2 Jubilee Way for a time due to a group of people obstructing the carriageway but disruption was kept to a minimum.
Outside of the town protesters are reported to have "superglued" themselves to another section of the A20 and are holding up cars there.
Protesters also hung giant banners showing the Extinction Rebellion "XR" emblem from Dover Castle and the iconic white cliffs.
Five million vehicles and almost 12 million passengers pass through Dover every year, making it one of the busiest ports in Europe.
