Currently run by Severn River Crossing Plc, the bridge will return to public ownership when the firm has collected a fixed sum of money from tolls, expected to be around 2017.
After the crash Network Rail said there had been a problem at the crossing a year ago, with the barrier rising and falling slowly, but it had been fixed and it was in full working order.
