A man has died in a fatal crash at Arcadia on Sunday, September 3.
Police believe the man was driving north on the Goulburn Valley Fwy when he lost control of his vehicle and crashed into a tree near Dawson Rd sometime overnight.
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
