Sadly, there is nothing unusual about a fatality on any road.
Sure there is. It may seem like people die on roads every day (and they do), but the road network is gigantic. It's much more than one road, and each fatal accident occurs under its own special circumstances. No agency wants a fatal to occur on their roads, but unfortunately they do. They'll study every fatal in great detail to see if there is anything that can be done to ensure that the accident never happens again. That said, sometimes there isn't anything that can be done (Drunk Drivers, etc.), but we (traffic engineers) still want to study the accident to figure out what could possibly be done to keep it from happening again.
Also, the Chausee is in fact the original access to the park (seen as Cedar Point Rd on google maps) As such, it is definitely not a private road, and is of major interest to the City of Sandusky. Learn more about it here.
