CAMPAIGNERS are demanding major improvements to a Hampshire commuter route after two motorcyclists were killed in a three-vehicle crash.

Police are still investigating the cause of the accident, which occurred on the A326 Marchwood Bypass at its junction with Twiggs Lane.

But the collision, coupled with other deaths over the years, has sparked an online petition that has already been signed by more than 1,900 people.

The petition has been launched by motorcyclist Kyle Hall, 34, of Butts Ash, Hythe, who uses the A326 every day.

Mr Hall wants Hampshire County Council to make the Twiggs Lane and Staplewood Lane junctions left-turn-only to cut the crash risk.

The circumstances surrounding the latest accident remain unclear but the petition says several other motorcyclists have been killed at the junction in the past decade.

It adds: “At least four others have passed away due to accidents on other stretches of this road.

“The two junctions need to be made left-turn-only, meaning vehicles are only able to turn left into these roads and left out of them.

“If we can stop another person losing their life at these junctions, then the lives we have lost already will not have been lost in vain.”

The petition is also calling for improvements to the 1km stretch of road between the two junctions, including solid white lines to prevent people overtaking.

As reported in the Daily Echo, the latest accident occurred on Wednesday at 6.15am.

Police say a Mercedes Sprinter van was involved in a collision with two motorcycles - a Honda and a Yamaha. Both bikers, a 38-year-old man from Gosport and a 49-year-old man from Southampton, died at the scene.

Police are appealing for witnesses to the accident, which closed the A326 for six hours.

Marchwood county councillor David Harrison said: “There might well be issues relating to the layout of the junction and, if so, I would expect the county council to address these.”

A county council spokesperson added: “Officers from the county council-led Casualty Reduction Partnership will be working with the police to establish the circumstances of the accident and take appropriate action.”
