An air ambulance attended the scene at Johnstown at around 5pm.
An air ambulance was called to a serious crash that closed the A483 for hours.
The helicopter, two land ambulances, two rapid response paramedic cars and police were called to the collision involving a biker on the northbound carriageway at J2 for Johnstown just before 5pm.
Between J1 for Ruabon and J3 at Croesfoel, all lanes of the road were blocked while emergency personnel handled the situation.
Drivers are advised to avoid the region as a result of the closure, which caused an eight-mile congestion to form from the J5 for Mould Road in Wrexham to the A5 in Chirk.
