Gardai are advising motorists to avoid the N52 between Blue Ball and Kilcormac following a serious collision.
Emergency services were called to the scene of a crash shortly before 8pm.
As Gardai deal with the situation they have taken the decision to restrict the road to one lane.
A stop/go system is in place on the N52 in the area as a result.
It is unclear at this time if serious injuries have occurred.
More as we get it.
10pm : The road has now re-opened and no serious injuries have been reported.
