A junction in Drumsillagh near Belturbet has been described as a "death trap".
Independent Councillor Brendan Fay says people are very vulnerable due to the lack of a right turning lane at the busy junction on the N3.
It follows a number of incidents, including a serious crash two years ago where a truck driver received life-changing injuries.
Concerns have been raised about the speed of traffic along the road and the lack of protection for vehicles that are slowing to turn.
A survey on the road has now been completed and Councillor Fay says a right hand turn lane would allow motorists to turn safely "without taking their life into their own hands":
