A 19-year-old motorcyclist died Wednesday night in Lebanon after he crossed the center line and struck an oncoming vehicle, state police said.

Police and rescue workers were called about 7:30 p.m. to the 100 block of Champion Street, a curved stretch of road that borders Milton Pond on the Maine-New Hampshire border.

Killed in the crash was Nathan Parker of Lebanon, who was riding at a high speed and struck a Chevy Impala when he crossed the center line as he came around a corner.

The female driver and children inside the Impala were not injured, police said.
