Easter 2012 - roadworks remaining in place for

0: M4 14-15 (near Hungerford) - Renewing drainage and safety barriers

Narrow lanes with 50mph speed limit - 6.6 miles of roadworks - Moderate delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed because safety barrier is incomplete.

1: M4 J7-8/9 (near Windsor) - Replacing worn out joints

Narrow lanes with 50mph speed limit - 2.9 miles of roadworks - Moderate delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed for safety because of the proximity of open excavations.

2: A31 Canford Bottom (near Ferndown) - Roundabout improvements

Narrow lanes with 30mph speed limit - 1.2 miles of roadworks - Moderate delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed for safety because of the proximity of open excavations.

3: M62 J25-28 (near Leeds) - Ducting, installation of gantries and new drainage works.

Narrow lanes with 50mph speed limit - 23 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed for safety because of the proximity of open excavations.

4: M1 J10-13 (near Luton) - Upgrade to "managed motorway" hard shoulder running. Junctions 11 and 12 are also being improved.

Mix of contraflow and narrow lanes with 50mph speed limit - there will continue to be three lanes in each direction - 22 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Speed limit needs to stay in place because safety equipment has had to be disabled during the roadworks. Temporary reinstatement of this safety equipment would take much longer than the Easter holiday.

5: M25 J29 - 30 (near Brentwood) - Widening motorway to four lanes

Narrow lanes with 50mph speed limit - 12.2 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed for safety because of excavations, broken carriageway and incomplete safety barrier.

6: M4 J1/J2-J3 (near West London) - Temporary weight limit

7: M25 J21a-23 (near St Albans) - Widening motorway to four lanes

Narrow lanes with 50mph speed limit - 11.3 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Restrictions needed for safety because of excavations, broken carriageway and incomplete safety barrier.

8: M4 J19-20 (near Bristol) - Preparing to open 'managed motorway' hard shoulder for traffic and introduce variable speed limits

Narrow lanes with 50mph speed limit - 9.5 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Narrow lanes are needed to keep traffic away from open excavations, some barriers have been moved back for the holiday period where possible.

10: M25 J9-10 (near Cobham) - Construction of slip roads for new motorway services

Narrow lanes and hard shoulder closure with 50mph speed limit - 3.2 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: The restrictions still provide four lanes in each direction and making changes over Easter weekend could be more dangerous because regular road users are familiar with the layout of this long-term scheme.

11: A38 (near Bodmin) - Embankment stabilisation

Narrow lanes with 30mph speed limit - 3 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Instability of road edge means traffic has had to be moved away from edge into narrow lanes..

12: M50 J1-2 (near Tewkesbury) - Replacement of and repairs to viaducts

Reduced from two to one lane in both directions, with 40mph speed limit - 3 miles of roadworks - Nil to slight delays expected. Reason roadworks cannot be lifted for holiday period: Contraflow has to stay in place because the eastbound viaduct is being demolished and reconstructed.
