Police are investigating a pedestrian crash in Orielton overnight where a car collided with a pedestrian on the Tasman Highway at about 11.55pm.

Sadly the pedestrian, a 16-year-old boy from Berriedale, died at the scene.

Police received multiple calls from motorists who stopped and assisted at the scene.

Initial inquiries indicate that a vehicle travelling on the Tasman Highway at Orielton has struck the boy who was lying on the road surface.

The driver of the vehicle stopped immediately and contacted police and emergency services.

Tragically the boy was deceased on arrival of emergency services.

The Tasman Highway remains closed while police conduct investigations into the crash.

As part of the investigations, it is believed the boy was travelling in a blue Mazda Tribute in the Orielton area prior to the crash.

Inquiries are continuing and police are appealing for witnesses to the crash and anyone who saw the blue Mazda Tribute around midnight to come forward.

Traffic travelling in the area is being diverted via Brinktop Road and Fingerpost Road through Richmond.

Our condolences go out to the family and loved ones of the boy and a report will be prepared for the coroner.
