Traffic is almost at a standstill this morning on the A303 at the junction for the A34 at Bullington Cross.
Sadly, one of the drivers was pronounced dead at the scene and as a result, the M3 southbound carriageway is closed between junctions 8 and 9.
This closure is expected to remain for several hours to allow for our investigations.
Drivers are being advised to allow extra time for their journeys.
