The A40 on the Golden valley is closed completely on the way to Gloucester.
Both lanes of the Gloucester-bound carriageway are shut after an incident on the busy dual carriageway.
Police have confirmed that the closure was put in place between J11 of the M5 and Elmbridge Court Roundabout after a woman fell from a bridge over the road.
She is being attended to by an ambulance crew and may have sustained injuries to her pelvis
Update 21:00 – The road has now reopened.
