Virginia State Police are investigating a fatal two-vehicle crash Thursday night on the Springfield Interchange.
Three people died in the accident, which occurred around 7 p.m. Thursday on the I-495 Beltway flyover ramp that leads to I-95 South.
"A tractor-trailer in the travel lane was stopped in traffic when it was rear-ended by a pickup truck. All three occupants of the pickup truck died at the scene. The driver of the tractor-trailer was not injured in the crash," Virginia State Police said in a release Thursday night.
The cause of the crash is still being determined.
As of 8:30 p.m., the flyover ramp remained closed and traffic is being diverted.
