One person was killed Saturday night in a fiery two-vehicle crash on Interstate 95 in Fairfax County, the Virginia state police said.

The crash occurred about 8 p.m. in the northbound HOV lanes near Exit 170, said state police spokeswoman Corinne Geller. The impact caused one of the vehicles to catch fire, she said.

No name or address was available for the victim.

The cause of the crash was not immediately known, and Geller said it was under investigation late Saturday night.

The crash shut down the High Occupancy Vehicle lanes, but they had reopened by shortly after 10 p.m., Geller said.

I-95 is one of the most heavily traveled roads in the eastern half of the country and is the principal north-south thoroughfare along the Atlantic seaboard.

The site of the crash was just south of the exits in the Springfield area of Fairfax County that lead to Interstate 395 and Interstate 495, according to Geller.
