MARION ­— A section of Route 6 near the Wareham-Marion town line was shut down for hours Saturday night following a severe single car crash.

Marion Police say that calls came in at approximately 6:51 p.m. of a crash on Route 6 near Gilda’s Stone Rooster. Fire and EMS units from the town also responded to the crash.

Upon arrival, first responders located a 2006 Pontiac sedan in the lane closest to the woods on the north side of the roadway. The vehicle was on all four wheels when authorities arrived, but police say it appears that it rolled over at one point during the crash and possibly struck a tree.

Marion firefighters extricated the sole occupant of the vehicle, a 28-year-old Rochester resident, who was transported to Tobey Hospital and subsequently airlifted to Rhode Island Hospital. Police are withholding the driver’s identity pending notification of family members.

Witnesses say the Pontiac was traveling west on Route 6 when it swerved to avoid a car pulling out of Gilda’s Stone Rooster. That’s when the driver apparently lost control of the vehicle and went off the roadway. Police say it does not appear the two vehicles collided at any point.

Route 6 was shut down for about three hours as authorities worked the scene. Officers from the Rochester and Wareham Police Departments were requested to the scene to assist with traffic.

The accident is currently under investigation by Sgt. Jeffrey Habicht, Officer McAssey and Massachusetts State Police. The Massachusetts State Police Accident Reconstruction Team and Massachusetts State Police Detectives are assisting in the investigation.

The driver’s current condition is not known at this time.
