Some motorists trapped overnight were caught in treacherous conditions on the M23 in Sussex and on the A23 in Kent
Here are the details of some of the roadworks planned in the South for the coming week.
Ryanair should have compensated passengers whose flights were cancelled because of volcanic ash in 2010, the EU's top court has found.
An accident on the M25 anticlockwise in Buckinghamshire has closed a lane at junction 16 for the M40. It's caused congestion stretching back to junction 17 for the A412 (Maple Cross).
The A4130 at Milton Hill in Oxfordshire is closed causing delays due to an accident and recovery work in both directions near the B4017 (the Steventon turn off).
There are lengthy delays on the M25 clockwise in Surrey between junction 10 for the A3 (Wisley Interchange) and junction 11 for the A317 (Chertsey) due to an earlier accident. It's causing congestion to junction 9 for Leatherhead.
The accident happened at 10:50 this morning and traffic was stopped for a short time to removed vehilces from the outside lane to the hard shoulder.
Traffic easing and long delays cleared after overnight roadworks overran earlier between J6 for Basingstoke and J5 for Hook.
All three lanes on the M3 Northbound between J6 A30 / A339 (Basingstoke) and J5 A287 / B3349 (Hook) have re-opened. But there is congestion back to J8 A30 / A303 (Andover).
Overnight works overran. Lane one reopened around 7:00 and lanes two and three reopened around 7:10.
Queueing traffic due to accident on M25 clockwise at A282 (QE2 Bridge), congestion on M25 to Before J30 A13 (Lakeside / Tilbury).
Two toll booths are closed at the end of the bridge after a lorry struck one of the barriers.
A32 in both directions closed due to flooding between A31 / Northfield Lane / Winchester Road (Chawton Roundabout) and Newton Lane / Mary Lane.
The Golden Pheasant pub tell us flooding is still across the road in the village.
Queueing traffic and three lanes closed due to overrunning roadworks on M3 Northbound between J6 A30 / A339 (Basingstoke) and J5 A287 / B3349 (Hook). In the roadworks area.
