Motorists have been hit by delays of up to 14 hours through Kent to get to the Port of Dover, with many holidaymakers being stuck in traffic overnight.
Port officials said delays built up due to understaffing of French border posts during heightened security checks.
The port warned of road delays of five to 10 hours, and Kent Police said there could be continued disruption for another 36 to 48 hours.
Police are flying in water for stranded motorists by helicopter.
P&O Ferries said there were estimated waiting times of up to 12 hours via the A20/M20, and up to three hours on the A2/A256, in addition to two hours at the port.
