Fatal crash at Arcadia

The vehicle appears to have gone over the top of roadside barriers and into trees on a median strip between the north and south lanes of the freeway.

A passer-by came across the crash just after 7.30am Sunday and called emergency services.

The driver, a Tullamarine man, 44, was the sole occupant of the vehicle.

He died at the scene.

On Sunday morning, the north-bound lane of the freeway remained closed in the area, with traffic diverted from Moorilim Rd and through Murchison.

The south-bound lane remained open.

The crash happened only a few kilometres south of the part of the road that turns from a highway into a freeway.

The circumstances surrounding the crash are yet to be established and the investigation remains ongoing.

Anyone who witnessed the crash, has dashcam/CCTV footage or information is urged to contact Crime Stoppers on 1800 333 000 or make a report online at www.crimestoppersvic.com.au
