THE M27 was shut for hours after a woman plunged from a bridge last night.

The road was reopened at about 1am this morning and an investigation into the incident will continue today.

Police have now confirmed that a woman died in the plunge.

The westbound carriageway was closed at junction 3 Nursling following the incident, which happened at about 6.30pm.

South Central Ambulance Service medics rushed to the scene in two ambulances and a rapid response vehicle.

A spokesman said nine people had been taken to Southampton General Hospital for treatment for shock.

It is thought they had all been travelling along the motorway at the time of the incident.

Matt Wellings, 21, was travelling from Milton Keynes to Bournemouth and has been sat in gridlocked traffic for more than an hour.

He said: “It has just been constant the emergency services that have gone past.”

“There are about seven or eight cars involved – it looks like there has been an accident as well as something else happening.

“There are about three or four cars in the middle lane stationary and another two or three on the hard shoulder.

Another motorist said: "I hit delays on the M27 and I must have seen at least eight police cars at the scene next to a bridge.

"Motorists cut off their engines as traffic barely moved - there was a large screen that was at least 50 metres long."

A police statement advised motorists to avoid the area.

The road was initially closed at junction 5 Southampton Airport but this section was reopened earlier.
