Police in Bethlehem say they're investigating a deadly crash that killed one motorist.

It happened just after 3:30 Sunday morning.

Officials say 24-year-old Joshua Kortze of Bushkill Twp. died after his car failed to negotiate a turn on the eastbound ramp on Route 22 from north Route 378.

Police say Kortze's car slid across the grass shoulder off the roadway before crashing into a concrete median.

He was transported to a nearby hospital where he later died of his injuries.
