A woman is in a serious but stable condition after being airlifted to hospital following a crash on the M11 yesterday.
A silver Citroen C5 estate and a silver and black Mitsubishi Shogun collided at around 11.30am on the northbound carriageway between junctions seven for Harlow and eight for Bishop's Stortford.
The Shogun ended up leaving the carriageway and striking a tree.
The driver, a 26-year-old woman from Margate, was airlifted to the Royal London Hospital.
The northbound track of motorway was closed to allow the air ambulance to and for forensic collision investigators to gather evidence.
Essex Police are appealing for witnesses to the incident to contact PC Paul Lindup at Chigwell Road Policing Unit on Essex Police 101.
