Chaos is expected for Bank Holiday travellers, both on the road and rail, as buses are expected to replace many train services throughout the country.
The RAC has also predicted that music festivals in Leeds, Reading, Glasgow and Cheshire will result in jam-packed roads, with Friday evening expected to be the peak travel time. The Notting Hill Carnival and Rugby League Challenge Cup Final at Wembley will also clog up London roads on Saturday.
The RAC said the M6 in the Lake District, the M55 towards Blackpool, the M5 southbound in the West Country and the A303 around Stonehenge in Wiltshire are all likely hotspots for traffic congestion.
Although the Highways Agency said it had completed 22 sets of roadworks ahead of the holiday weekend, some remain on a number of busy routes. The northern section of the M25, parts of the M4 and the A46 in the West Midlands will still be slowed due to the delays.
With 42 different sets of engineering work happening on railways, the Liberal Democrats said replacement buses would run on 1,000 miles of rail routes over the weekend.
