Three people were hospitalized with serious injuries after a two-car crash that closed Highway 16 near West Floating Feather Road Monday evening.

A teenage girl and a teenage boy who were traveling west on Floating Feather Road suffered injuries that were first believed to be life threatening, according to the Ada County Sheriff's Office. Sheriff's spokeswoman Andrea Dearden said late Monday that the boy's injuries are serious but survivable. The girl is in critical condition but is stable.

Their car was crossing Highway 16 just after 6:45 p.m. when it was struck by a car being driven north on the highway by an adult female. That woman was taken by air ambulance to Saint Alphonsus Regional Medical Center with serious injuries. The teens were taken by ground ambulance to St. Al's.

Highway 16 was closed in both directions until just before midnight. A crash reconstruction expert from the sheriff's office spent several hours at the scene of the wreck; authorities have not determined who was at fault.
