The crash involved four vehicles and was initiated when a semi-truck traveling southbound crossed the median and collided with three vehicles heading northbound.
The woman, who was a passenger in one of the affected cars, was confirmed dead at the scene. In addition to the fatality, several other individuals involved in the accident suffered minor injuries. First responders arrived quickly to provide care, but the severity of the crash proved fatal for one and fortunately less harmful for others.
Authorities are actively investigating the circumstances surrounding the crash, with the primary focus on why the semi-truck crossed the median. Police have not yet confirmed whether alcohol or drugs may have played a role in the incidents leading up to the crash. Witness reports described the collision as violent, with debris and dirt scattered across multiple lanes of the highway.
The collision caused significant disruption, as US-23 was closed in both directions between Nixon Road and Pontiac Trail for several hours. As a result, traffic was heavily affected, impacting thousands of drivers trying to navigate the area.

The freeway was not reopened until late Friday night at approximately 11 p.m., allowing vehicles to return after the area was declared safe.
Eyewitnesses reported observing the semi-truck losing control right before it veered into oncoming traffic. One witness noted that a white SUV was forcefully pushed deep into the woods as a result of the collision, highlighting the crash’s impact.

As the investigation unfolds, officials are focused on gathering additional data and witness testimonies to piece together the full sequence of events that led to this sorrowful incident. As always, safety remains a top priority as investigators work diligently to understand the cause of such tragic events on roadways.
