Two drivers were injured in a head-on crash at the intersection of Routes 47 and 176 in Woodstock, causing a portion of Route 47 to be closed for about an hour, officials report.

The Woodstock Fire/Rescue District responded to a call at 12:35 p.m. at that intersection for a reported crash with injuries. First responders arrived at a three-vehicle crash north of the intersection, with two vehicles with “moderate front-end damage” found “nearly 600 feet apart in separate roadside ditches,” Woodstock Fire/Rescue District Public Information Officer Alex Vucha said in a news release.

A preliminary investigation found that the cars crashed head-on before one of the vehicles continued off the road, striking another vehicle that was parked off the road, Vucha said.

Both drivers were transported to Northwestern Medicine Huntley Hospital with reported minor injuries. The third, parked vehicle involved was vacant during the crash.

The crash, which happened in an active construction zone, caused a closure on Route 47 in both directions for approximately an hour, according to the release.

The McHenry County Sheriff’s Office is investigating the crash.
