The helicopter ran into a powerline and crashed Thursday morning on the Mississippi River near East Alton, Illinois, officials said.

The crash happened at about 11 a.m. about a mile and a half south of the Clark Bridge, said Missouri Highway Patrol spokesman Cpl. Dallas Thompson.

The Mississippi River has reopened to vessel traffic north of St. Louis after closing because a helicopter crashed into a barge on Thursday, killing two people, the U.S. Coast Guard said on Friday.
