A woman was being treated in the intensive-care unit at a hospital in Boise on Wednesday following a collision a day earlier at the intersection of state Highway 75 and Ohio Gulch Road north of Hailey.

According to a press release from the Blaine County Sheriff’s Office, county communications received a report of a two-vehicle collision at the intersection around 2:45 p.m. Tuesday. Sheriff’s deputies and Wood River Fire & Rescue and the Ketchum Fire Department responded to the scene.

An initial investigation determined that Aurelia Sproule, 63, of Ketchum was driving a 2004 Orange Honda Element when she attempted to turn left onto southbound Highway 75 from Ohio Gulch Road. Sproule pulled directly into the path of a 2011 Nissan Murano driven by Lindy R. Brewer, 68, of Hailey. Brewer struck Sproule’s vehicle on the driver’s side, causing Sproule’s vehicle to rotate. Sproule was not wearing a seatbelt, and upon impact was ejected from the vehicle, according to the Sheriff’s Office.

Brewer was treated for minor injuries at St. Luke’s Wood River Medical Center, while Sproule was first transported to the Wood River Medical Center and then transported by air ambulance to Saint Alphonsus hospital in Boise, where she remained in the intensive care unit as of press deadline Wednesday.

Both directions of the highway were closed for about an hour and 15 minutes.

“I would like to remind everyone to please drive safely and use caution on the roadways. This is a busy weekend for our community with high traffic volume,” Sheriff Steve Harkins said in the press release. “Let’s keep this weekend a safe and uneventful one for our first responders.”
