The A55 from Junction 31 eastbound and Junction 32 has reopened in both directions following the earlier police incident.
Police say they were called at 8.46am to reports that a man had fallen off a bridge at Brynford onto the eastbound carriageway of the A55.
The road was closed in both directions as police, paramedics, and two air ambulances attended the scene.
The man was airlifted to the Royal Stoke University Hospital with serious injuries at around 10.30am.
Very sad news. I hope he makes a good recovery. Was very heartening to hear stories of people who had stopped to help and support him.
