Dover TAP is back in place due to heavy traffic and strong gale force winds in the harbor.
There were significant queues on the coastal roadway of the A20 which was closed between junction 13 of the M20 in Folkestone and the A260 in Hawkinge.
The closure was intended to prevent queuing traffic in the Roundhill Tunnel.
There were 30 minute delays on the M20 and over three kilometers of congestion.
Huge queues formed at the port of Dover, which resulted in the activation of “Dover Tap”.
The problems were made worse by stormy weather which saw the Met Office put in place a gale warning from 4 p.m.
Strong gale force 9 winds were turning southwesterly but are expected to abate.
Across the county there have been numerous reports of problems due to Storm Barra.
On the rails, a fallen tree near Sittingbourne caused delays for commuters.
Network Rail apologized for the delay, which hit services around 6 p.m., as the tree was removed at 6:40 p.m.
Brady Rd in Lyminge, near Folkestone has been blocked due to a fallen tree from Farthing Common to Woodland Road.
Near Ashford, White Hill was partially blocked for the same reason from the A28 Canterbury Road to the A251 Buck Street.
A tree also fell near The Rose and Crown pub in Hartlip, near Sittingbourne, which blocked Lower Hartlip Road.
And at Snodland, drivers have been advised to approach Sandhole with caution due to falling power cables at Hollow Lane.
Meanwhile, motorists caught in traffic jams on the approach to Dover were advised to follow designated detours and plan ahead.
National Highways advised drivers to exit the M20 at junction 13 and merge onto the A259 at Churchill Avenue and head east towards the A260 Canterbury Road before turning north on the A260 and turning Head to the Spitfire Way roundabout junction in Hawkinge.
Dover TAP is a temporary traffic management system that queues trucks bound for the port in the left lane of the A20 after the Roundhill tunnel to prevent Dover from being congested.
A 40 mph speed restriction applies to all vehicles approaching Dover via the A20 which operates all day, every day.
