Crews from Harwinton and Harwinton West Side volunteer fire departments rushed over. They used extrication tools to free one of the drivers as the emergency scene unfolded.

The Nissan driver, Roseann Dennerlein, 64, of Riverton, was taken to a local hospital with serious injuries. She was later pronounced dead.

The Honda CR-V driver had minor injuries and went to a nearby hospital for evaluation. Responders worked at the scene for a while as they stabilized the vehicles and handled the extrication.

Check in with local police or radio stations for any road closures or detours before heading out.
