Firefighters responded to two crashes in the eastbound lanes of Interstate 90 within minutes and a mile of each other Thursday evening in Huntley, officials reported.

The Huntley Fire Protection District responded to the first crash at 5:18 p.m. at mile marker 48 along I-90. While responding, crews saw another crash about a mile east and directed additional units to that crash, according to a Huntley Fire Protection District news release.

Two people were involved in the first crash, with one man in serious condition and another person declining further medical treatment. The man was taken to Advocate Sherman Hospital in Elgin.

One lane was closed for almost an hour, according to the release.

The second crash was reported three minutes after the first one at mile marker 47. First responders arrived to “a heavily damaged vehicle in the middle lane with the adult male driver trapped inside,” according to the release.

Firefighters worked for about 35 minutes to free the driver, who was taken to Advocate Sherman Hospital with life-threatening injuries. A medical helicopter originally was requested, but it was not available due to the weather, officials said in the release.

Officials believe another car, possibly a semitruck, may have been involved in the crash. No other drivers were found by firefighters.

Both crashes are being investigated by the Illinois State Police. Illinois Tollway Authority HELP trucks, an off-duty Sleepy Hollow police officer and Illinois State Police assisted in responding to the crashes. The Hampshire Fire Protection District covered the Huntley department while the Huntley department was responding to the incidents.
