A construction worker was injured and transported to a trauma center after he was struck by a vehicle in a work zone in Marengo Wednesday morning.

The Marengo Fire and Rescue Districts and Marengo Police Department responded around 11:06 a.m. Wednesday to West Grant Highway and Park Drive for a pedestrian struck by a vehicle.

Marengo Fire and Rescue Districts Communication Specialist Alex Vucha said paramedics arrived within minutes and found a single-vehicle crash involving a construction worker near the intersection.

The adult male victim, identified as an Illinois Department of Transportation worker, was lying on the pavement injured, Vucha said.

A LifeNet medical helicopter was initially placed on standby but was canceled.

The worker was transported by ambulance to OSF Saint Anthony Medical Center in Rockford, a Level 1 trauma center, with moderate, non-life-threatening injuries.

A bystander told Lake and McHenry County Scanner that the worker was a flagger in the work zone. He could not stand up after the collision.

Vucha said the driver of the vehicle, an adult female, was uninjured.

She was transported to Northwestern Medicine Hospital in Woodstock for a psychological evaluation.

Grant Highway, also known as Route 20, was closed in both directions for 30 minutes, Vucha said.

The Marengo Police Department is investigating the cause of the crash. The department did not immediately respond to a request for comment.
