Much has been written recently of driving speeds, speed limits and safe driving, but nothing to my knowledge has been written about building safe roads; in particular making safe modifications to existing roads.
Take Lyons-Mill City drive for instance. It is an older well-built road. The corners, except for one in particular, are engineered and built so that simply pointing a vehicle into the corner the auto seemingly drives itself through. This effortless cornering occurs at any speed one chooses. Even at 60, 70, or 80 MPH simply point a car into the corners and it will enter and exit in its own lane - except for one.
East bound, the road lulls a person into a feeling of false confidence. Since there is no warning I suspect that more than a few, including myself, have discovered the bad corner. There was one young driver I heard of who found it the hard way some years ago. Traveling east he entered the second half of the 'S' curve at the western end of Franks Lumber at well over 60 MPH. As he exited the corner the road no longer guided his car along the marked lane as all previous corners had!
At that location the eastbound lane is an addition, a modification, to the original roadway. Made to create room for a turn lane, the new lane is not correctly built. The super (the tilt to aid cornering) drops off too soon and/or sharply. As a vehicle exits that curve it is still under the sideways, shear, centrifugal force of cornering when the road flattens out. The result is the marked lane and natural line of travel at the exit of the corner take two different paths. IE: A car following the natural line of travel suddenly leaves the paved road. Adding to the hazard there's a power pole standing in the natural path of the car.
I'm certain the driver fell victim to;
I'm equally as certain no liability was assigned to the engineers who designed the substandard modification. I further assume no one asked if those engineers had a responsibility to build and/or modify roads in a manner that maintains the quality, drive ability, of the original road. That those who modified that corner were not;
