A Suffolk man died Sunday evening in a single-vehicle motorcycle crash on Interstate-664.

It happened southbound at 8:54 p.m., according to state police spokeswoman Sgt. Michelle Anaya.

She said the driver of the 2007 Harley-Davidson motorcycle was traveling at a high rate of speed when he cut in front of another driver at the exit ramp at College Drive, lost control, hit the guardrail and was thrown from the motorcycle.

The driver, 57-year-old Haywood Lee Day, of the 5400 block of Sports Club Run, died at the scene, Anaya said. It is unknown if alcohol played a factor in the crash.
