The bodies of a man and woman have been discovered underneath a landslide near Beaminster Tunnel, according to reports.
It is understood the couple lay buried in their car for more than a week before fire crews discovered them last night.
Police searching for two missing Somerset people confirmed they have found a car buried in a landslide at the tunnel.
There has been no official confirmation as yet whether anyone has been found inside the vehicle.
It has been reported that a man in his 70s and woman in her 60s, from Taunton and Crewkerne, were reported missing and were believed to have been in the Beaminster area.
A statement from Avon and Somerset Constabulary said: "Police searching for two people missing from Somerset have recovered a vehicle in Dorset.
"Enquiries into the missing man and woman suggested they were in the Beaminster area on Saturday July 7 and Dorset Police were requested to check the area of Beaminster tunnel.
"Dorset Police have found a car under a large volume of earth and mud.
"At this time it is too early to speculate about the outcome but families have been informed and are being supported by family liaison officers."
A joint statement from Dorset Police and Dorset Fire and Rescue Service said: “At approximately 6.30pm yesterday (Monday 16 July 2012), Dorset Fire and Rescue Service were contacted by Avon and Somerset police regarding the partial collapse of Beaminster Tunnel.
"Crews were subsequently sent to investigate the area, and following a period of excavation discovered a vehicle under a large volume of earth and mud.
“At approximately 7.20pm yesterday (Monday 16th July 2012), Dorset Police were advised that Dorset Fire and Rescue Service personnel had discovered a car under a large volume of earth outside the entrance of Beaminster tunnel.
"The road has been closed and a cordon has been put in place while emergency service staff attempt to excavate the vehicle."
The A3066 has been closed in both directions between the B3163 Clay Lane junction and the B3164 junction since Saturday, July 7, when a landslip was caused by heavy overnight rain.
