JFTR, I-81 goes from Wellesley Island in NY (at the Canadian border) to Dandridge TN. Strangely enough, both ends of that road are in those states’ Jefferson Counties.
I realize it goes that far north and essentially ends at the border, and have been on that strip many times.
However, there is precious little traffic going north of Syracuse, so the death toll up there isn’t nearly what it is south of Syracuse. Plus, the road is far more wide open than south of Syracuse. It’s a gorgeous drive. In the summer and fall.
The section between Syracuse and Cortland was particularly bad for fatal accidents and absolutely insane drivers.
I didn’t realize that the southern end of I-81 was also in a Jefferson County as well. Interesting.
