A dog has been reunited with his owner after escaping from a car during a crash on the M25.
There are massive jams on the M25 this afternoon as thousands head away for the Bank Holiday. Long queues mean delays on the entire southern section with two-hour delays from Dartford to Heathrow.
The junction around the M11 is badly hit as well.
Gridlock at the junction with the M3 means many drivers are diverting to the M4. It follows a slow start to the getaway earlier today.
It's a route used by more than a hundred thousand drivers a day. The Dartford Crossing is one of the biggest pinch-points for the south-east road network. Today the Government said it will do a detailed study of two final options for a new crossing over the Thames.
But some debate whether it's needed. David Johns reports, speaking to Roads Minister Robert Goodwill and Thurrock Council leader John Kent (Lab).
Two lanes are closed and traffic is queueing on the M25 clockwise between Clacket Lane Services and junction 6 A22/B2235 (Godstone) with congestion to junction 5 M26/A21 due to an accident involving two lorries and a car.
One lane closed due to broken down vehicle on M25 anticlockwise at J2 A2 (Darenth Interchange).
Two lanes closed and queueing traffic due to vehicle fire on M25 anti-clockwise between J16 M40 and J15 M4.
TRAVEL: The entry slip onto the clockwise M25 at J9 is closed due to the crane fire. 2 lanes are still closed on the main carraigeway.
Drivers travelling through roadworks on the M25 between Kent and Surrey will get to use 4 lanes from next week when the hard shoulder opens as an extra lane. From Wednesday morning motorists travelling between junctions 5 and 6 will use the hard shoulder as a permanent extra lane.
John Martin, Highways Agency Senior Project Manager said: "The improvements on the M25 in Kent and Surrey are part of the £1.7 billion of investment into roads in the South East by 2021.
The new smart motorway will provide extra capacity and offer more reliable journeys for the 140,000 drivers that use this stretch of road every day. I'm particularly pleased that the southern section of the M25 has opened well ahead of planned completion this winter.
"Ahead of the opening next week, I would like to ask drivers to get smart and find out more about how to use it, the types of signs and signals they will see and what to do in the event of a breakdown."
