The Westchester district attorney says 26-year-old Alberto Plasencia has been charged with second-degree murder.
He was arrested Tuesday, nearly nine years after the fatal crash.
Marie McSweeney, of Queens, was driving south on the Sprain Brook Parkway when a chunk of asphalt 10 inches long slammed through her windshield and hit her in the head in 2004.
The car crashed and the 48-year-old McSweeney was killed. Her 87-year-old mother survived.
The district attorney's office says new information came to light in 2009 that led to Plasencia's arrest. A spokesman would not elaborate.
