The A1 at Grantham has been closed due to a serious incident that happened just before 8am this morning on Dysart Road.
Lincolnshire police have confirmed that a man has died at the scene of a crash that involved three lorries.
There was significant traffic disruption in the area after the crash as a section of the A1 between the A52 and the A607 junctions was closed as a necessity whilst the circumstances were being investigated.
The A1 Northbound has now reopened and the Southbound is expected to reopen around 4pm.
Lincolnshire police are asking motorists in the area to be patient and follow diversion.
