Police received a call about the single-vehicle crash at the intersection of Fairbairn Avenue and Mount Ainslie Drive, Campbell, about midnight.

Firefighters were first on the scene and put out the fire.

Officers have so far been unable to identify the driver, or even the make or type of the car involved.

The car appears to have come down Mount Ainslie Drive, gone through the intersection with Fairbairn Avenue and crashed head on into a stone retaining wall on the other side of the road.

A spokeswoman said police were investigating the circumstances of the accident and would prepare a report for the coroner.

Fairbairn Avenue was closed to traffic in both directions until about 5am, when the eastbound lane was reopened. The westbound lane was reopened by 6.15am.

Police asked any one who might have seen anything to contact Crime Stoppers on 1800 333 000 or at act.crimestoppers.com.au.

It is the second death on a Canberra road this year, and comes after a motorcycle rider died after crashing into a tree on Cotter Road near Stromlo.

In a separate incident, paramedics took two people to Canberra Hospital after a three-car crash on Hindmarsh Drive at Symonston shortly after 9am.
