Video filmed by Twitter user @welshmummabear shows cars in a queue at Dover.
Dover port said on Twitter that freight and car traffic was being processed steadily, regardless of challenging weather conditions and high seasonal volumes of traffic, but coaches were suffering significant delays.
It said “despite considerable planning,” the additional coach bookings taken on by ferry operators over the Easter period had impacted operations at the port.
The BBC reported roads leading to the port had become gridlocked.
The port apologized for the delays, and said it had provided food and drinks to coach passengers waiting in border queues. Credit: @welshmummabear via Storyful
