A 33-year-old man suffered critical, life-threatening injuries after he was struck by a vehicle while riding his bicycle near Libertyville Saturday afternoon, the sheriff said.

The Libertyville Fire Department and Lake County Sheriffโ€™s Office responded around 12 p.m. Saturday to the area of Rockland Road west of Rockland Lane in unincorporated Libertyville for a vehicle crash with injuries.

Deputies arrived to find a crash involving a car and a bicyclist on Rockland Road at the Des Plaines River pedestrian and bicycle trail.

Lake County Sheriffโ€™s Office Deputy Chief Christopher Covelli said a 33-year-old man from Mundelein was found critically injured.

A preliminary investigation shows the bicyclist was traveling northbound on the Des Plaines River Trail when he attempted to cross West Rockland Road.

He was struck by a westbound Toyota Prius, driven by a 39-year-old man from Gurnee, Covelli said.

The impact appeared to have thrown the bicyclist onto the vehicleโ€™s front windshield before he fell to the ground.

Covelli said the bicyclist was transported to a local hospital with critical, life-threatening injuries.

The driver of the Toyota, as well as a child passenger, were uninjured.

Rockland Road was shut down for several hours while crash investigators investigated the scene.

The Lake County Sheriffโ€™s Office Technical Crash Investigations Team continues to actively investigate the circumstances of the collision, Covelli said.
