Heartfelt tributes have continued to pour in for three victims killed in horror crashes over the weekend.

Already this year, there have been six fatal crashes in the county and 11 across the entire Thames Valley region.

Serious collisions have also injured pedestrians and caused significant damage to buildings in the last few weeks.

Detective chief inspector Mike Bettington of Thames Valley Police said: "The winter months often sees an increase in serious road traffic collisions.”

It comes as emergency services were called to the northern bypass between the Headington Roundabout and Marsh Lane near Marston shortly before 4pm yesterday. 

The road was partially blocked with traffic moving slowly on approach.

In the latest fatalities, both men were behind the wheel when they crashed on roads in Banbury and Oxford respectively.

The woman had exited her car on the hard shoulder of the motorway when she was struck and killed by a lorry.

Thames Valley Police has not released the names of any victims and has made no arrests as of yet.

Emotional tributes have been left to the victims by family, friends and well-wishers over the past few days.

Flowers have been laid at the junction in Banbury where one victim, a man named locally as Lee, died on Saturday morning.

The 33-year-old crashed a blue Subaru Impreza into a roundabout on Orchard Way at 1.35 am and flipped the car.

Lee, who was reportedly a father of three, suffered a severe head injury and died at the scene of the crash.

Tributes have also been paid online, where his death has been described as “dreadfully sad” and “a great loss”.

Police said the “extremely tragic incident” near the Lewknor junction happened after she stepped out of her vehicle.

It came on a day of double tragedies, with another fatal crash that evening along the A4142 near Headington Roundabout.

The driver, a man in his 30s, careered off the Eastern Bypass Road in a white Hyundai IX35 and smashed into a tree.

He was taken to the John Radcliffe Hospital, along with a passenger in his 40s, but later died of his injuries.

A police spokesman said roads policing officers had been “particularly busy” since January 1.

On Tuesday, a red Vauxhall Corsa crashed through the glass front of Millbrook Barbers near Wantage.
