A Rhode Island man has been taken to a Brunswick hospital after apparently falling sleep at the wheel of a tractor trailer early Thursday and being rescued by boat.

At 5:39 a.m., Deputy Robert Mayer of Sagadahoc County Sheriff’s Office along with first responders from Woolwich Fire and Rescue departments responded to the crash at the dike on Route 1 in Woolwich.

The driver, Steven R. Brown, 60, of Providence, Rhode Island, was traveling northbound on Route 1. It appears he fell asleep and went off the road into the dike where he was trapped until rescued by boat. The tractor-trailer, registered to Medline Inc.,was transporting medical supplies. Brown was transported to Mid Coast Hospital with non-life-threatening injuries.

Sagadahoc County Emergency Management, Maine Departments of Transportation and Environmental Protection also responded.

The crash remains under investigation. At this time, neither speed nor alcohol appear to be factors.
