The driver was pronounced dead at the scene.

In Millbury, a Harley Davidson motorcycle went off Route 146 southbound and into the median.

The driver, Clifford Giovannucci, 48, of South Grafton, was thrown from the motorcycle and landed in the road, state police said.

Giovannucci was taken to UMass Medical Center in Worcester, where he later died.

Both crashes are under investigation by state police.
