Rail passengers are being warned of disruption over Easter due to engineering work, but the majority of motorway roadworks will be lifted.
Highways England said it would remove 459 miles of roadworks by Thursday, with 97 miles’ worth staying for safety reasons.
There are no trains in or out of London Euston station from Friday to Monday.
However, Network Rail said it would be the “quietest” engineering programme for “many years”.
When is the worst time to travel?
The RAC and traffic data company Inrix expect jams to be at their worst on Good Friday, particularly between 11:00 and 16:30 BST.
They predict the M5 southbound, west of Bristol between Junction 16 and Junction 19, to be congested as drivers head for Devon and Cornwall.
The M25 from Bromley through the Dartford Tunnel, the M6 north between Preston and Lancaster and the M62 west between Leeds and Manchester are also likely to see delays of about an hour.
RAC spokesman Rod Dennis said the weekend would see “lengthy queues in some spots”.
From 18-22 April
Dan Croft from Inrix warned journeys “could take up to three times longer than usual”.

The predictions are based on data from previous Easter getaways as well as planned roadworks.
Where are the roadworks?
Almost all motorways and major roads will be free of roadworks by Thursday morning, Highways England said.
It aims to lift or complete as many as possible by 06:00 and they will not re-start until 00:01 on Tuesday.
However, more than 97 miles of roadworks will still be in place.
A spokesman said: “To help people have smoother journeys we have removed as many roadworks as possible, leaving only essential work in place. However, it is not possible to remove all roadworks due to safety reasons.”
Roadworks staying in place
Longest sets over Easter weekend
Is my train running?
Rail engineering works worth about £100 million will mean cancelled trains and replacement buses over the Easter weekend.
However Network Rail said most services would be “unaffected” and it was the “quietest engineering programme for many years”.
Chief executive Andrew Haines said: “We know that our railway is up to 50% quieter than usual over bank holidays so doing work at this time of year minimises our impact on passengers.”
Routes that will face disruption between Friday and Monday include:
- The west coast main line route will be closed near London, Preston and Glasgow
- No trains to or from London Euston
- No trains to or from London Fenchurch Street, with services diverted to Liverpool Street and replacement buses between Barking and Aldgate East
- Replacement buses between BristolParkway, Chepstow and Newport from Friday to Monday
- Replacement buses between Shenfield, Southend Victoria and Southminster
- Replacement buses between Birmingham International and Rugby
- Replacement buses between Sheringham and Cromer, with Sheringham station closed
- No LNER services between Edinburgh and Glasgow on Saturday, Sunday and Monday, but ScotRail services will run
