(KRON) — A woman was arrested after a wrong-way driving incident on Interstate 280 turned deadly on Saturday afternoon near San Mateo, according to the California Highway Patrol, Redwood City.

A white 2010 Ford sedan was traveling north in the southbound lanes of I-280 around 2:38 p.m. when it crashed into a black 2019 BMW SUV heading south in the fourth lane, near State Route 92. The driver of the BMW was pronounced dead at the scene of the crash. She was described as a Caucasian woman in her 40s. A 14-year-old boy was in the front passenger seat of the BMW, and he was taken to Stanford Medical Center with “major” injuries.

The person behind the wheel of the Ford was later identified as Constellatia A. Martin, a 24-year-old woman from Campbell. Martin was arrested on a suspicion of vehicular manslaughter. She was taken to Stanford for treatment of major injuries, CHP confirmed. Police do not yet know if drugs or alcohol were factors in the crash, and a toxicology report is pending.

Three of the lanes were closed in the area for over an hour, but CHP reopened the lanes at 6 p.m. Traffic in the area is heavy, and drivers are suggested to take alternate routes. Anyone with information about the crash is asked to call Office M. Duque at 650-779-2700.

Another wrong way crash took place earlier Saturday morning in the North Bay. A driver died in Marin County after a red pickup truck heading north in the southbound lanes collided with another vehicle.
