A wrong-way crash late Friday night shut down Ga. 316 at Winder Highway in Gwinnett County, authorities reported.

The accident happened about 10:30 p.m. in the eastbound lanes of the highway near Dacula, Channel 2 Action News reported. Traffic lanes in both directions were closed as emergency crews responded to the scene.

"A wrong-way vehicle struck another vehicle head-on," Sgt. Rich Long of the Gwinnett County Police Department told the AJC at 10:45 p.m. "There were two entrapments."

Six people were injured, two critically. One patient, a 12-year-old child, was transported to Children's Healthcare of Atlanta at Egleston.

Other details were not immediately available.

It was the second wrong-way crash on a metro Atlanta highway in less than 24 hours and the third in less than two weeks.

The earlier accident happened about 3:30 a.m. Friday in the southbound lanes of Ga. 400 between Holcomb Bridge and Northridge roads in Sandy Springs.

Carlyn Emily Royball, 22, of Alpharetta, was driving northbound in the southbound lanes when she struck a sport-utility vehicle head-on, Sandy Springs police spokesman Steve Rose said. Royball, a 2008 graduate of Milton High School, was killed.

The SUV's driver, Kelly Stevens, the morning show co-host on B98.5 FM, survived the wreck. He was taken to Grady Memorial Hospital, where he underwent surgery Friday for broken bones, Channel 2 reported.

Police were seeking to determine how Royball ended up going the wrong way on the highway.

In the first wrong-way crash of recent days, Frampere Ingle got on Ga. 400 at Lenox Road in Buckhead going southbound in the northbound lanes around 4:15 a.m. Aug. 15. Ingle slammed head-on into a car driven by Eric Hanks. Both Ingle and Hanks were killed, police said.
