Two thousand people have been injured as more than 1,000 vehicles were involved in a series of crashes in thick fog on the A249 Sheppey crossing in Kent.
Sixty of those hurt in the collisions, which took place between 07:15 and 08:05 BST, are thought to have serious injuries.
Early reports suggested up to 400 vehicles were involved, but police later said more than 1,000 had crashed.
Ninety ambulances and sixty fire engines were at the scene on the southbound carriageways. About 2,000 people have minor injuries.
Ten witnesses said visibility was very poor but drivers were approaching the crossing with no lights.
Firefighters said they had used hydraulic cutting equipment to release fifty people from their vehicles.
