A woman motorcyclist is seriously ill in hospital after her bike crashed into bollards on the A26 near the Cliffe Industrial Estate, Lewes.
The 25-year-old, from Eastbourne, suffered serious head and leg injuries in the smash, which happened at 4.15pm on Thursday (October 9).
She was airlifted to the Royal Sussex County Hospital, Brighton, by the Kent, Surrey and Sussex Air Ambulance.
The A26 was closed between its junction with the A27 Lewes by-pass at Southerham Roundabout and the northern portal of the Cuilfail Tunnel at Malling Street.
Traffic jams built up in all directions around Lewes as emergency services dealt with the incident. The road was finally re-opened almost three hours later at 7pm.
Anyone who saw what happened is asked to email firstname.lastname@example.org or phone 101, quoting Operation Brookside.
