Harwinton, CT (February 28, 2026) – A woman was killed following a head-on collision on Burlington Road in Harwinton on Friday afternoon, February 27. Emergency units responded to the scene around 3 p.m. after reports of a serious crash on Route 4.
State police said a vehicle driven eastbound by 63-year-old Roseann Dennerlein crossed into the westbound lane and collided head-on with an oncoming vehicle. The second vehicle was being driven by Nicholas Maccione, who suffered only minor injuries in the crash.
Dennerlein was pronounced dead as a result of the collision. No additional details about the events leading up to the crash were immediately released.
Burlington Road was closed between White Oak Drive and Route 72 for several hours while crews worked to clear the scene and remove damaged vehicles. The roadway reopened later Friday evening.
The crash remains under investigation by authorities.
Our condolences are with Ms. Dennerlein’s family and loved ones.
Why Head-On Crashes on Two-Lane Roads Can Be So Severe
Head-on crashes often result in serious or fatal injuries because both vehicles are moving toward each other at the time of impact. Even brief lane departures can leave drivers with little opportunity to avoid a collision.
Two-lane roadways may present added risks due to limited shoulders, curves, or changing road conditions. When a vehicle crosses the center line, the force of impact is typically much greater than in other types of crashes.
In cases like these, investigators review vehicle positions, roadway layout, and driver actions just before the collision. These factors help explain how a vehicle entered oncoming traffic and why the crash had such serious consequences.
