YORK — A rear-end collision in front of the Lobster Barn Seafood and Grill in York forced police to shut down Route 1 for more than an hour Wednesday afternoon and sent two people to local hospitals with unknown injuries.

Sgt. Steven J. Spofford said 44-year-old Gina-Marie Ambrosino, of York, was attempting to make a left-hand turn into the seafood restaurant when a 2001 four-door Volvo operated by 33-year-old Brian Decato struck her from behind.

Ambrosino, who was driving a 2006 Mercury Mountaineer sport utility vehicle, was transported to York Hospital. Decato had to be extricated from his vehicle by firefighters. Decato’s vehicle was totaled. He was transported to Portsmouth Regional Hospital.

The cause of the crash remains under investigation. The crash was reported at 4:23 p.m. Route 1 reopened to traffic around 5:40 p.m.
