Drivers have been warned that the worst traffic jams of the bank holiday weekend are likely to hit on Friday night, as people head off for an extended break.
The Highways Agency said there will be restrictions due to roadworks in 25 areas over the weekend, though it has finished or suspended other works. A three-mile length of roadworks at the A20 Roundhill Viaduct near Folkestone port in Kent is likely to spark some of the worst problems.
INRIX, which provides traffic information, said Manchester would see the worst congestion on Friday, between 5pm and 6pm. TheRAC also said traffic would mount over Friday afternoon and main roads would suffer jams.
London is likely to have problems on Saturday as football's Champions League final - between Manchester United and Barcelona - takes place at Wembley and Twickenham hosts the Aviva Premiership rugby final.
The RAC said routes heading for bank holiday jams include the M25 and roads leading from it, routes to the west of England including the M4, M5 and A303, roads to North Wales and the Lake District as well as routes to Blackpool.
Drivers who want to bypass such jam-prone areas could use ajourney planner to find routes that avoid them.
RAC patrol ambassador of the year Kevin Andrews said: "Traffic volumes to holiday resorts always pick up at the start of schools' half-term breaks along with the spring bank holiday and, if the sun shines, RAC expects heavy traffic as families head for the beaches. I recommend drivers get away early and allow plenty of time to avoid the jams."
