Police have appealed for witnesses following a fatal road crash on the A13 near Stanford-le-Hope.
A driver died when his car was in collision with a heavy goods vehicle parked in a lay-by on the London-bound carriageway shortly before 11am.
Both carriageways were closed initially while emergency vehicles were called to the scene.
The eastbound carriageway reopened shortly after 12 noon but the London-bound carriageway will be opened and closed periodically to allow traffic to pass while police carry out investigations. The investigation is likely to last another three hours.
Any witnesses or anyone with information about events leading to the crash should contact the Essex Police Serious Collision Unit on 101 or email [email protected]
