SLIPPERY ROCK TWP — The driver of an SUV that collided with a pickup truck Wednesday morning at the intersection of Route 8 and Branchton Road will be charged with a stop-sign violation.

Melissa Henthorn, 41, of Brady Township was traveling east on Branchton Road in her 2012 Ford Expedition — with her three young children — when she collided with a 2004 Dodge Ram traveling north on Route 8 driven by 63-year-old Thomas Grossman of Brady Township at 8 a.m.

State police said their investigation has indicated Henthorn is at fault and will receive a summary violation.

State police investigator Lt. Eric Hermick said as of now, it does not look like gross negligence was involved in the accident.

“Right now, she’s facing a traffic violation,” Hermick said.

Grossman was partially ejected from his vehicle. He was flown by medical helicopter to Allegheny General Hospital in Pittsburgh. He was in serious condition as of this morning.

Henthorn was flown by medical helicopter to UPMC Presbyterian, where she was in good condition this morning.

The children’s injuries were described as minor. Hermick said they were checked out at the scene and released to their father. He said he was not sure if their father took them for further evaluation.

According to birth announcements, two of the children are 5 and 10 years old. The third child is a preteen, but the exact age could not be confirmed.

The accident Wednesday was the second in two weeks at that intersection, which has a history of bad crashes.

On July 24, six people were hurt, two seriously, when a Toyota Prius filled with young adults and a Chevy pickup collided. Two of those injured remain hospitalized in Pittsburgh.

State police said the crash happened when Devaughn DiSalvo, 19, of Cranberry Township, who was driving the car westbound on Branchton Road, pulled from the stop sign.

The car traveled into the intersection and was struck by the truck, northbound on Route 8, driven by Darrell Lamotte Jr., 56, of West Sunbury.

Both drivers and four passengers in the car were injured.

Evan Parke, 21, of Butler and Alexandra Weckerly, 20, of Wexford, who were riding in the back seat of the Prius, were flown by medical helicopter to a Pittsburgh hospital. Police said both remain hospitalized. A spokesman for Allegheny General Hospital said that Weckerly was in serious condition in the trauma unit, but had no information on Parke.

DiSalvo and two other passengers — 19-year-old Haley Rosemeyer and 19-year-old Andrew Broadus, both of Pittsburgh — and Lamotte were all treated at different hospitals and later released.

Police said their investigation continues but they expect to charge DiSalvo with unspecified traffic violations.

The intersection was previously put under scrutiny in 2003 following one of the deadliest car crashes in Butler County history.

On July 7, 2003, Ejub Grcic, a Bosnian-born trucker, ran a stop sign on Branchton Road.

Grcic’s overweight tractor-trailer struck a car, killing five members of a North Carolina family who were visiting in the area.

The state Department of Transportation and the National Transportation Safety Board both studied the intersection after that crash and found that a traditional stoplight was not warranted, though PennDOT recommended other improvements.

In 2003, pavement markings were placed on Route 8 and vegetation was trimmed.

In 2004, a light was installed that flashes yellow for traffic on Route 8 and flashes red for traffic on Branchton Road.

Slippery Rock Township Supervisor Paul Dickey said Wednesday that he did not know the details of that morning’s crash, but generally thinks the intersection is safe.

“We felt pretty good with the improvements we did a couple years ago,” he said about adding the flashing signal in 2004.

According to data collected by PennDOT in 2013, an average of between 4,600 and 5,000 vehicles drive through that intersection on Route 8 each day. About 1,700 vehicles drive through the intersection on Branchton Road daily.

The stretch of Route 8 is open to local traffic only during a PennDOT bridge replacement project about 4 miles south of the intersection. The work is scheduled to be finished in October.
