A Monroe County man died Wednesday night from injuries he sustained the previous day in a motorcycle crash on Route 22 westbound in Bethlehem.

Lehigh County Coroner Daniel A. Buglio said Robert Swain, 29, of Coolbaugh Township, was pronounced dead at 7:09 in the Lehigh Valley Hospital-Muhlenberg, Bethlehem.

The coroner said the death was due to multiple traumatic injuries Swain had sustained.

Buglio said Swain was the operator of a motorcycle that crashed into a tractor trailer at 1:40 p.m. Tuesday.

State police at the Bethlehem barracks were summoned to investigate the crash.
