A day at work on the Tri-State Tollway in Alsip ended in tragedy Monday.
About 12:30 p.m. two tollway workers were collecting debris on the shoulder of the road when one of them was struck by a semi-trailer.
"While he was outside his vehicle and walking back to his vehicle he was struck by a semi-truck pulling a semi-trailer," said Illinois State Police Master Sgt. Don Orseno.
It's not clear how fast the semi was traveling, but it didn't stop. The tollway worker was pronounced dead at the scene.
"There were witnesses as well as partner he was out there working with that called in that tollway worker was struck," Orseno said.
A tollway spokesperson declined to provide any information about the worker, saying in a statement:
"The Illinois Tollway extends its deepest sympathy to his family and friends."
Signs along the tollway remind drivers to yield to workers.
"They're encouraged and obligated to slow dawn," Orseno said of drivers on the tollway. "Change lanes when applicable to avoid tragedies like this."
