Two people were seriously injured in separate roadway crashes that shut down eastbound Sunrise Highway Monday night, one in Nassau and one in Suffolk, authorities said.

In Bellmore, a motorcyclist going south on Bedford Avenue crashed with a northbound truck that was trying to make a left onto Sunrise Highway about 7:30 p.m., shutting down lanes for hours, Nassau police said.
