Two people were injured in a head-on crash that shut down Route 11 in Naples for more than two hours Saturday morning.

The Cumberland County Sheriff’s Department said a 2001 Subaru, driven by Courtney Blais, 25, of Bridgton, crossed the centerline of the road near the intersection of Edes Falls and Casco roads around 10:15 a.m. and hit a 2002 Ford F-150, driven by Paul Arsenault of Portland.

Sheriff’s deputies said Blais suffered life-threatening injuries and was flown by helicopter to Central Maine Medical Center in Lewiston. Hospital officials said Saturday night they didn’t have information on her condition.

Arsenault and his passenger – his wife, Pamela Arsenault – were taken by ambulance to Bridgton Hospital with what officials said were not life-threatening injurie.

The sheriff’s office said the crash remains under investigation.
