Gardaí are renewing an appeal for witnesses following a fatal collision on the M18 southbound between J12 and J13, Gort to Ennis Road.
A red Ford Transit van and a white articulated Volvo truck were involved in the accident on June 5 at 12:48 pm.
Ennis Gardaí are particularly anxious to speak to a male driver of a dark colour Opel Insignia saloon car.
It is believed that the man may have witnessed the fatal collision.
The sole occupant of the van, a man in his 60s, was pronounced dead at the scene a short time later.
The male driver of the truck was uninjured.
The investigation is on-going.
Investigating Gardaí are asking for witnesses or anyone with information to contact Ennis Garda Station on (065) 6848100 or the Garda Confidential Line 1800 666 111.
