An 18-year-old Holley resident was seriously injured this morning when her car veered off a road in the Orleans County Town of Gaines and hit a concrete bridge structure, sheriff’s deputies reported.

Jillian Marie Troy was driving north along Eagle Harbor-Waterport Road at about 5 a.m. when she apparently lost control of her car, which crossed the center line and ran off the west side of the roadway. It then hit the structure that carries the road over Otter Creek.

Firefighters from Albion and Carlton freed Troy from the wreckage. She was then taken by helicopter to Strong Memorial Hospital, where she’s in guarded condition, deputies said. She was alone in the car.
