Sinn Féin MLA Caoimhe Archibald has expressed her sympathies with the family of a man who died.
Ms Archibald said:
“I would like to express my sympathies to the family and friends of the man who has died as a result of this morning's crash.
"This is the second death on the A6 in weeks and as we enter into the winter months, I would urge all road users to exercise care and caution on the roads at all times and to allow for extra travelling time if conditions are poor."
"The A6 is a very important commuter and haulage route so I will be meeting with the Infrastructure Minister to discuss the broader road safety issues on this stretch of the road." .
