One person was killed in a series of crashes that shut down the outer loop of the Perimeter on Monday morning.

Multiple vehicles were involved in three separate accidents at Church Street just before 4 a.m., according to DeKalb County police. In the third and final wreck, a box truck rear-ended a tractor-trailer.

The driver of the box truck was taken to a local hospital, where he was pronounced dead, police spokesman Sgt. J.D. Spencer told Channel 2 Action News. He was identified by the DeKalb County Medical Examiner’s Office as 52-year-old Roberto Aguirre Salgado of Jonesboro.

The crash happened at I-285 northbound at Church Street in DeKalb County.

All northbound lanes of I-285 were blocked south of U.S. 78 while authorities were on scene. During the three-hour shutdown, authorities were diverting traffic off the interstate at Memorial Drive.

Lanes were reopened just before 7 a.m., but traffic was heavy between I-20 and U.S. 78 throughout the morning drive, according to the WSB 24-hour Traffic Center.
